Abstract:Let $\on_{k \in \nz}$ be an orthonormal system on some
$\sigma$-finite
measure space $(\Om,p)$. We study the notion of cotype with respect to
$\Phi$
for an operator $T$ between two Banach spaces $X$ and $Y$, defined by
$\fco T := \inf$ $c$ such that
\[ \Tfmm \pl \le \pl c \pll \gmm \hspace{.7cm}\mbox{for
all}\hspace{.7cm}
(x_k)\subset X \pl,\]
where $(g_k)_{k\in \nz}$ is a sequence of independent and normalized
gaussian variables. It is shown that this $\Phi$-cotype coincides with
the usual notion of cotype $2$ iff \linebreak
$\fco {I_{\lin}} \sim \sqrt{\frac{n}{\log (n+1)}}$ uniformly in $n$
iff there is a positive $\eta>0$ such that for all
$n \in \nz$ one can find an orthonormal $\Psi = (\psi_l)_1^n \subset
{\rm span}\{ \phi_k \p|\p k \in \nz\}$ and a sequence of disjoint
measurable
sets $(A_l)_1^n \subset \Om$ with
\[ \int\limits_{A_l} \bet \psi_l\rag^2 d p \pl \ge \pl \eta \quad
\mbox{for all}\quad l=1,...,n \pl. \]
A similar result holds for the type situation.
The study of type and cotype with respect to orthonormal systems
of a given length provides the appropriate approach to this result.
We intend to give a quite complete picture for orthonormal systems
in measure space with few atoms.

Abstract: Let $E$ be a Banach space and, for any positive integer $n$,
let ${\cal P}(^nE)$ denote the Banach space of continuous
$n$-homogeneous polynomials on $E$. Davie and Gamelin showed that
the natural extension mapping from ${\cal P}(^nE)$ to
${\cal P}(^nE^{\ast\ast})$ is an isometry into the latter space.
Here, we investigate
when there is a natural isomorphism between ${\cal P}(^nE)^{\ast\ast}$
and ${\cal P}(^nE^{\ast\ast})$. Among other things, we show
that if $E$ satisfies: \break
(a) no spreading model built on a normalised
weakly null sequence has a lower $q$-estimate for any $q < \infty,$
(b) $E^{\ast}$ has RNP, and
(c) $E^{\ast}$ has the approximation property,
then ${\cal P}(^nE)$ has RNP for every $n$. Moreover, if $E$ satisfies
(a) and is such that $E^{\ast\ast}$ has both the RNP and the
approximation
property, then ${\cal P}(^nE)^{\ast\ast}$
and ${\cal P}(^nE^{\ast\ast})$ are isomorphic for every $n$. We also
exhibit
a quasi-reflexive Banach space $E$ for which ${\cal P}(^nE)^{\ast\ast}$
and ${\cal P}(^nE^{\ast\ast})$ are isomorphic for every $n$.
Related work has been done recently by (i) M. Gonzalez, (ii) M.
Valdivia, and (iii) J. Jaramillo, A. Prieto, and I. Zalduendo.

Abstract:It is proved that every function of finite Baire index on a
separable
metric space $K$ is a $D$-function, i.e., a difference of bounded
semi-continuous functions on $K$. In fact it is a strong $D$-function,
meaning it can be approximated arbitrarily closely in $D$-norm, by
simple $D$-functions. It is shown that if the $n^{th}$ derived set of
$K$ is non-empty for all finite $n$, there exist $D$-functions on $K$
which are not strong $D$-functions. Further structural results for the
classes of finite index functions and strong $D$-functions are also
given.

Abstract:We use the methods of Burkholder, Gundy,
and Silverstein to study maximal
functions and square functions arising in the construction of the
conjugate function on the finite dimensional torus.
Using Brownian motion, we obtain dimension-free weak type (1,1)
estimates that enable us to prove an analog
of the classical Privalov's Theorem for conjugate
functions on the disk, in the general setting of a
locally compact abelian group with an ordered dual group.
In order to do this, we study the structure of measurable orders
on locally compact abelian groups, extending the work of
H\"older and Hahn. The final result complements previous work of
Bochner, Helson and Lowdenslager.

Abstract:We examine some structural properties of (injective and
projective)
tensor products of $\ell_p$-spaces (projections, complemented
subspaces,
reflexivity, isomorphisms, etc.). We combine these results with
combinatorial arguments
to address the question of primarity for these spaces and their duals.
Our main results are:
\medbreak
\item{(1)} If $1<p<\infty$, then $B(\ell_p)\approx B(L_p)$ ($B(X)$
consists
of the bounded linear operators on $X$).
\medbreak
\item{(2)} If ${1\over p_i}+{1\over p_j}\leq1$ for every $i\neq j$, or
if
all of the $p_i$'s are equal,
then $\ell_{p_1}\hat{\otimes}\cdots \hat{\otimes}\ell_{p_N}$ is
primary.
\medbreak
\item{(3)} $\ell_p$ embeds into
$\ell_{p_1}\hat{\otimes}\cdots \hat{\otimes}\ell_{p_N}$
if and only if there exists
$A\subset \{1,2,\cdots,n\}$ such that
${1\over p}=\min\{\sum_{i\in A}{1\over p_i},1\}$.
\medbreak
\item{(4)} If $1\leq p<\infty$ and $m\geq1$, then the space of
homogeneous
analytic polynomials ${\cal P}_m(\ell_p)$ and the symmetric tensor
product of $m$ copies of $\ell_p$ are primary.

Abstract:We consider the problem of complex
interpolation of certain Hardy-type subspaces of K\"othe
function spaces. For example, suppose $X_0$ and $X_1$ are
K\"othe function spaces on the unit circle $\bold T,$ and
let $H_{X_0}$ and $H_{X_1}$ be the corresponding Hardy
spaces. Under mild conditions on $X_0,X_1$ we give a
necessary and sufficient condition for the complex
interpolation space $[H_{X_0},H_{X_1}]_{\theta}$ to coincide
with $H_{X_{\theta}}$ where $X_{\theta}=[X_0,X_1]_{\theta}.$
We develop a very general framework for such results and our
methods apply to many more general sitauations including the
vector-valued case.

study whether any two of them are isomorphic to each other, and show
that the nest algebras in the trace class have bases. We construct
three non-isomorphic examples of nest algebras in $c_1$; present a new
proof of the primarity of $c_1$ (Arazy, [Ar1], [Ar2]), and prove that
$K(H)$, and the nest algebras in $B(H)$ are primary.

Abstract:Necessary and sufficient oscillation conditions are given
for a weakly convergent sequence
(resp. relatively weakly compact set)
in the Bochner-Lebesgue
space $\l1$ to be norm convergent
(resp. relatively norm compact),
thus extending the known results for $\rl1$.
Similarly,
necessary and sufficient oscillation conditions are given
to pass from weak to
limited (and also to Pettis-norm) convergence in $\l1$.
It is shown that tightness is a
necessary and sufficient condition to pass from
limited to strong convergence.
Other implications between several modes of convergence
in $\l1$ are also studied.

Abstract:Let $M$ be a non-degenerate Orlicz function such that there
exist
$\ep > 0$ and $0 < s < 1$ with $\su M(\ep s^i)/M(s^i) <
\infty$. It is shown that the Orlicz sequence space $h_M$ is
isomorphic to a subspace of $C(\om^\om)$. It is also shown
that for any non-degenerate Orlicz function $M$, $h_M$ does not embed
into $C(\al)$ for any $\al < \om^\om$.

This is the abstract of the paper "Banach spaces with the $2$-summing
property" by A. Arias, T. Figiel, W. B. Johnson and G. Schechtman. The

Abstract: A Banach space $X$ has the $2$-summing property if
the norm of every linear operator from $X$ to a Hilbert space is
equal to the $2$-summing norm of the operator.
Up to a point, the theory of spaces which have this property
is independent of the scalar field: the property is
self-dual and any space with the property is a finite dimensional
space of
maximal distance to the Hilbert space of the same dimension.
In the case of real scalars only the real line and real
$\ell_\infty^2$ have the $2$-summing property. In the complex case
there are
more
examples; e.g., all subspaces of complex $\ell_\infty^3$ and their
duals.

Abstract:We characterize 1-complemented subspaces of finite codimension
in
strictly monotone
one-$p$-convex, $2<p<\infty,$ sequence spaces. Next we describe, up
to isometric isomorphism, all possible types of 1-unconditional
structures in sequence spaces with few surjective isometries. We also
give a new example of a class of real sequence spaces with few
surjective isometries.

Abstract:As is well known absolute convergence and
unconditional convergence for series are equivalent only in finite
dimensional
Banach spaces. Replacing the classical notion of absolutely summing
operators by the notion of 1 summing operators
\[ \summ_k || Tx_k || \leq c || \summ_k e_k
\otimes x_k ||_{\ell_1\otimes_{min}E}\]
in the category of operator spaces, it turns out that there are quite
different interesting
examples of 1 summing operator spaces. Moreover, the eigenvalues of a
composition
$TS$ decreases of order $n^{\frac{1}{q}}$ for all operators $S$
factorizing
completely through a commutative $C^*$-algebra if and only if the 1
summing norm
of the operator $T$ restricted to a $n$-dimensional subspace is not
larger than
$c n^{1-\frac{1}{q}}$, provided $q>2$. This notion of 1 summing
operators
is closely connected to the notion of minimal and maximal operator
spaces.

(Edward W. Odell (University of Texas)
and
Thomas Schlumprecht (Texas A. & M. University))
Also other participants of the Workshop can contribute to the
scientific
program. Moreover, it is not supposed to fill all the time by lectures;
many informal discussions in a fruitful working atmosphere are
expected.
************************************************************************
The conference fee is $ 250,- (or an equivalent). Reduced rate of
$ 220,- applies provided the registration form reached organizers
before March 15, 1994. The conference fee includes all local expenses

Subject: Missouri Conference Update
1) To date we have received registrations from over 200 participants
from
23 different countries. We can accomodate up to 300 participants.
We have received about 60 requests for contributed talks.
2) All those who applied for the dormitory package have been approved.
We can support some limited number of additional participants
for this package if registration is received before April 1.
3) It would be helpful for us if all those who are able to do
so easily can pay their registration fee before arriving.
4) Because of the size of the meeting, we cannot guarantee to

Travel Information
The travel information is provided to help you in making your
travel
plans. You may be able to take advantage of various discounted
air
fares if you make reservations soon, so we would encourage you to
take
action promptly. The material concerning travel and
motel
accommodations should be self-explanatory.
We also ask that you send back your registration form at your
earliest
convenience, so that we can start filling in the schedule of talks.
It
should also be noted that there is an upper limit to the number
of
participants we can accommodate so we may be forced to decline
late
registrations. There will be another mailing nearer the conference
in
which we give a more detailed schedule. If you want to give a 20 or
30
minute talk, your abstract should accompany your registration form.
We
ask that, if possible, you have your abstract prepared in TeX and
that
you send us both a hard copy and an electronic copy. Please try to
keep
your abstract short and to the point, and, in particular, not more
than
one page (a third to a half a page is much preferred). For joint
work,
please indicate the speaker with an asterisk (*). We will prepare
a
list of abstracts in alphabetical order by speaker. These will
be
distributed at registration. Also, there will be a registration fee
of
$40. It would assist the organizers if this is paid in advance;
of
course it is refundable in the event of non-attendance. The fee
is
waived for the main speakers and graduate students. Please make
your
check payable to: The University of Missouri, Dept of
Mathematics.
We also accept payment by Visa or Master Card.
Other information, about restaurants, use of e-mail, etc., will also
be
provided at registration.
Since this mailing is being sent to two different lists of
e-mail
addresses, it is possible that you will receive multiple copies of
it.
We apologize in advance for this inconvenience.
If you desire further information, please direct your queries to
the
account conf at esaab.cs.missouri.edu. Phone queries should go to
the
Math. Dept. office (314-882-6221). The Dept.'s fax number
is
314-882-1869.

Travelling to and from Columbia, Missouri
We describe here the principal means of access to and from
Columbia.
Details about getting around Columbia will be provided later.
CAR
The main highways through Columbia are Interstate 70 (I-70)
(east-west)
and US Highway 63 (north-south). I-70 runs east-west and connects
to
Kansas City to the west and St. Louis to the east. In particular,
St.
Louis airport (Lambert field) is situated about 18 miles west of
St.
Louis directly on I-70. It is about 110 miles from the airport
to
Columbia. From Kansas City International Airport take I-435 to
I-70:
it is about 150 miles. Columbia airport is 15 miles south of Columbia
on U.S. 63.
AIR
If flying, you can choose between flying to Columbia, St. Louis
and
Kansas City. Columbia airport is served by TWE from St. Louis and
by
Lone Star Airlines from Dallas/Fort Worth. It is about 15-20
miles
south of Columbia. We hope to run vans to pick people up there at
peak
times. There is also Midwest Airport Shuttle (314-874-4048)
which
charges $11 one-way with $1 extra per additional passenger to the
same
destination. Taxis are also available (Checker Cab Co. 449-4191).
Some
motels may also offer shuttle service.
>From St. Louis airport you may rent a car; see driving
instructions
above. Otherwise, there are two choices of public transportation.
Tiger Air Express Limousine service to Columbia (314-443-3544
or
800-333-3026) offers door-to-door service at $40 one-way,
with
departures at approximately one to two-hour intervals. Call to make
a
reservation. (We can make arrangements for overseas participants)
The
final departure from St. Louis is at 9:30 p.m. daily.
The Greyhound bus operates on the following schedule. Call Greyhound
to
make sure that this schedule is still valid.
Lambert Field to Columbia

Kansas City Airport is somewhat further from Columbia, (about a 3 hour
drive). It is also served by Tiger Air Express on a rather less
frequent schedule. Contact Tiger Air Express for details.

Motel Information
Participants from the US and Canada are asked to make their
own
reservations directly with the hotel or dormitory. Be sure to ask
for
the conference rate (you may need to mention that this is a special
rate
agreed upon with the Math. Dept. for the Analysis Conference).
Please
make your reservation before the release date (listed
below).
Participants from outside North America may contact the
conference
organizers and specify the accommodation required
The Johnston/Wolpers(Dorm) and Campus Inn are within walking distance
to
campus.

Funding Information
The conference will be supported by the National Science Foundation,
and
the University of Missouri. We are in the process of seeking
additional
funds and the final budget situation is not yet clear; we have
applied
for funds to cover at least some local expenses of all participants,
but
we will not know if we can do this for some time. Since we
are
expecting a large attendance, we would like those of you who have
other
sources of support to use these. We particularly hope to fund
graduate
students and recent Ph.D's who have no other sources of funding.
We have worked out a deal with the Dormitory which will enable us to
offer meals in the package if we have a sufficient number signed up by
Feb. 15. We are therefore, prepared to guarantee covering the expenses
for meals (breakfast, lunch and dinner)
and accommodation (at a rate equivalent to double occupancy) at
the Dormitory for the first 100 participants who register, pay their
registration fee and sign up for such a package before February 15,
1994.

Abstract:In this paper structure of infinite dimensional Banach spaces
is
studied by using an asymptotic approach based on stabilization at
infinity of finite dimensional subspaces which appear everywhere far
away. This leads to notions of asymptotic structures and asymptotic
versions of a given Banach space. As an example of application of this
approach, a class of asymptotic $l_p$-spaces is introduced and
investigated in detail. Some properties of this class, as duality and
complementation, are analogous to properties of classical $l_p$
spaces, although the latter is more ``regular'' than its classical
counterpart; in contrast, the property exhibited in the uniqueness
theorem is very different than for spaces $l_p$.

Abstract:We give elementary proofs of the theorems mentioned in the
title. Our methods rely on a simple version of Ramsey theory and a
martingale difference lemma. They also provide quantitative results:
if a Banach space contains $\ell^{1}$ only with a bad constant then
every bounded sequence admits a subsequence which is ``nearly'' a weak
Cauchy sequence.

Abstract:The question which led to the title of this note is the
following:
{\it If $X$ is a Banach space and $K$ is a compact subset of $X$, is it
possible to find a
compact, or even approximable, operator $v:X\to X$ such that
$K\subset\ol{v(B_X)}$?}
This question was first posed by P.G.Dixon [6] in connection with
investigating the problem of
the existence of approximate identities in certain operator algebras.
We
shall provide a couple
of observations related to the above question and give in particular a
negative answer in case of
approximable operators.
We shall also provide the first examples of Banach spaces having the
approximation property but
failing the bounded compact approximation property though all of their
duals do even have the
metric compact approximation property.

Abstract:The powerful concept of an operator ideal on the class of all
Banach
spaces makes sense in the real and in the complex case. In both
settings we may, for example, consider compact, nuclear, or
$2$--summing operators, where the definitions are adapted to each
other in a natural way. This paper deals with the question whether or
not that fact is based on a general philosophy. Does there exists a
one--to--one correspondence between ``real properties'' and ``complex
properties'' defining an operator ideal? In other words, does there
exist for every real operator ideal a uniquely determined
corresponding complex ideal and vice versa?
Unfortunately, we are not abel to give a final answer. Nevertheless,
some preliminary results are obtained. In particular, we construct
for
every real operator ideal a corresponding complex operator ideal and
for every complex operator ideal a corresponding real one. However,
we
conjecture that there exists a complex operator ideal which can not
be
obtained from a real one by this construction.
The following approach is based on the observation that every
complex Banach space can be viewed as a real Banach space with an
isometry acting on it like the scalar multiplication by the imaginary
unit $i$.

Abstract: In this article, we characterize the $UMD$--property of a
Banach space $X$
by ideal norms associated with trigonometric orthonormal systems.
The asymptotic behavior of that numerical parameters can be used to
decide
whether or not $X$ is a $UMD$--space. Moreover, in the negative case,
we
obtain a measure that shows how far $X$ is from being a $UMD$--space.
The main result is, that all described parameters are equivalent also
in the
quantitative setting.

Abstract:The framework of the paper is that of the full Fock space
${\Cal F}^2({\Cal H}_n)$ and the Banach algebra $F^\infty$ which can be
viewed
as non-commutative analogues of the Hardy spaces $H^2$ and
$H^\infty$ respectively.
An inner-outer factorization for any element in
${\Cal F}^2({\Cal H}_n)$ as
well as characterization of invertible elements in $F^\infty$ are
obtained. We also give a complete characterization of invariant
subspaces for the left creation operators $S_1,\cdots, S_n$ of
${\Cal F}^2({\Cal H}_n)$.
This enables us to show that every weakly (strongly)
closed unital subalgebra of $\{\varphi(S_1,\cdots,S_n):\varphi\in
F^\infty\}$
is reflexive, extending in this way the classical result of Sarason
[S].
Some properties of inner and outer functions and many examples are also
considered.

space which is isometric to a subspace of $L_{1/2}$ but is not

to a subspace of $L_1.$ The isomorphic version of this problem (posed
by S. Kwapien in 1969) is still open. Another example gives a Banach
subspace of $L_{1/4}$ which does not embed isometrically in $L_{1/2}.$
Note that, from the isomorphic point of view, all the spaces $L_q$ with
$q<1$ have the same Banach subspaces.

Abstract:The paper is devoted to two particular cases of the following

Let a Banach space $X$ has bases of both types and a subspace
$M\subset X^*$ contains the sequence of biorthogonal functionals
of some $\alpha$-basis in $X$. Does $M$ contain a sequence of
biorthogonal
functionals of some $\beta$-basis in $X$?
The following particular cases are considered:
$(\alpha, \beta)$=(Schauder bases, unconditional bases),
$(\alpha, \beta)$=(Nonlinear operational bases, linear operational
bases).
The paper contains an investigation of some of the spaces constructed
by
S.Belle\-not in ``The $J$-sum of Banach spaces'', J. Funct. Anal. {\bf

Abstract:A Banach space $E$ has the Grothendieck property if every
(linear
bounded) operator from $E$ into $c_0$ is weakly compact. It is proved
that, for an integer $k>1$, every $k$-homogeneous polynomial from $E$
into $c_0$ is weakly compact if and only if the space ${\cal P}(^kE)$
of scalar valued polynomials on $E$ is reflexive. This is equivalent
to the symmetric $k$-fold projective tensor product of $E$ (i.e., the
predual of ${\cal P}(^kE)$) having the Grothendieck property. The
Grothendieck property of the projective tensor product
$E\widehat{\bigotimes}F$ is also characterized. Moreover, the
Grothendieck property of $E$ is described in terms of sequences of
polynomials.
Finally, it is shown that if every operator from $E$ into $c_0$
is completely continuous, then so is every polynomial between these
spaces.

Abstract:Letting $E$, $F$ be Banach spaces, the main two results of
this paper
are the following: (1) If every (linear bounded) operator
$E\rightarrow F$ is unconditionally converging, then every polynomial
from $E$ to $F$ is unconditionally converging (definition as in the
linear case). (2) If $E$ has the Dunford-Pettis property and every
operator $E\rightarrow F$ is weakly compact, then every $k$-linear
mapping from $E^k$ into $F$ takes weak Cauchy sequences into norm
convergent sequences. In particular, every polynomial from
$\ell_\infty$ into a space containing no copy of $\ell_\infty$ is
completely continuous. This solves a problem raised by the authors in
a previous paper, where they showed that there exist nonweakly compact
polynomials from $\ell_\infty$ into any nonreflexive space.

Abstract:We prove that weakly unconditionally Cauchy (w.u.C.) series
and
unconditionally converging (u.c.) series are preserved under the
action of polynomials or holomorphic functions on
Banach spaces, with natural restrictions in the latter case. Thus it is
natural to introduce the unconditionally converging polynomials,
defined as polynomials taking w.u.C. series into u.c.\ series, and
analogously, the unconditionally converging holomorphic functions.
We show that most of the classes of polynomials
which have been considered in the literature consist of unconditionally
converging polynomials. Then we study several ``polynomial
properties'' of Banach spaces, defined in terms of relations of
inclusion between classes of polynomials, and also some
``holomorphic properties''. We find remarkable differences with the
corresponding ``linear properties''. For example, we show that a Banach
space $E$ has the polynomial property (V) if and only if
the spaces of homogeneous scalar polynomials
${\cal P}(^k\!E)$, $k\in{\bf N}$, or the space of scalar holomorphic
mappings
of bounded type ${\cal H}_b(E),$ are reflexive. In this case
the dual space $E^*$, like the dual of Tsirelson's space, is reflexive
and contains no copies of $\ell_p$.

Abstract:Let $(f_n)$\ and $(g_n)$\ be two sequences of random variables
adapted
to an increasing sequence of $\sigma$-algebras $({\cal F}_n)$\ such
that
the conditional distributions of $f_n$\ and $g_n$\ given ${\cal
F}_{n-1}$\ coincide, and such that the sequence $(g_n)$\ is
conditionally independent. Then it is known that $\normo{\sum f_k}_p
\le C \, \normo{\sum g_k}_p$, $1 \le p \le
\infty$\ , where the constant $C$\ is independent of
$p$. The aim of this paper is to extend this result to
certain classes of Orlicz and rearrangement invariant spaces. This
paper
includes fairly general techniques for obtaining rearrangement
invariant
inequalities from Orlicz norm inequalities.

Abstract:For each $S \in L(E)$ (with $E$ a Banach space) the operator
$R(S) \in
L(E^{**}/E)$ is defined by $R(S)(x^{**}+E) = S^{**}x^{**}+E$ \quad
($x^{**}\in E^{**}$). We study mapping properties of the correspondence
$S\to R(S),$ which provides a representation $R$ of the weak Calkin
algebra $L(E)/W(E)$ (here $W(E)$ denotes the weakly compact operators
on $E$). Our results display strongly varying behaviour of $R.$ For
instance, there are no non--zero compact operators in Im$(R)$ in the
case of $L^1$ and $C(0,1),$ but $R(L(E)/W(E))$ identifies isometrically
with the class of lattice regular operators on $\ell^2$ for
$E=\ell^2(J)$ (here $J$ is the James' space). Accordingly, there is an
operator $T \in L(\ell^2(J))$ such that $R(T)$ is invertible but $T$
fails to be invertible modulo $W(\ell^2(J)).$

functions. The main step of our construction, using a special sequence
of outer holomorphic functions, shows that a certain sequence space is
isomorphic to a complemented subspace of a weighted space of
holomorphic functions in two complex variables.
This example solves in the negative a well-known open problem raised
by Bierstedt, Meise and Summers.

Abstract:Let $X$ be a complex Banach space and let $J:X \to X^*$ be a
duality
section on $X$ (i.e. $\langle
x,J(x)\rangle=\|J(x)\|\|x\|=\|J(x)\|^2=\|x\|^2$).
For any unit vector $x$ and any
($C_0$) contraction semigroup $T=\{e^{tA}:t \geq 0\}$, Goldstein
proved that if $X$ is a Hilbert space and if $|\langle T(t)
x,J(x)\rangle| \to 1 $ as $t \to \infty$, then $x$ is an
eigenvector of $A$ corresponding to a purely imaginary eigenvalue.
In this article, we prove the similar result holds if $X$ is a
strictly convex complex Banach space.

board by ftp to ftp.math.okstate.edu or transmitting the commands

Abstract:The concentration of measure prenomenon roughly states that,
if a set
$A$ in a product $\Omega^N$ of probability spaces has measure at least
one half, ``most'' of the points of $\Omega^N$ are ``close'' to $A$.
We proceed to a systematic exploration of this phenomenon. The
meaning of the word ``most'' is made rigorous by isoperimetric-type
inequalities that bound the measure of the exceptional sets. The
meaning of the work ``close'' is defined in three main ways, each of
them giving rise to related, but different inequalities. The
inequalities are all proved through a common scheme of proof.
Remarkably, this simple approach not only yields qualitatively optimal
results, but, in many cases, captures near optimal numerical
constants. A large number of applications are given, in particular
in Percolation, Geometric Probability, Probability in Banach Spaces,
to demonstrate in concrete situations the extremely wide range of
application of the abstract tools.

Abstract: We present three methods to construct majorizing measures in
various settings.
These methods are based on direct constructions of increasing
sequences of
partitions through a simple exhaustion procedure rather than on the
construction of well separated ultrametric subspaces. The first scheme
of
construction provides a simple unified proof of the Majorizing
Measure Theorem for Gaussian processes and of the following fact. If
$A,B$
are balanced convex sets in a vector space, and if $A$ is sufficiently
convex, a control of the covering numbers $N(A,\varepsilon B)$ for all
$\varepsilon>0$ implies the (a priori stronger) existence of a
majorizing
measure on $A$ provided with the distance induced by $B$. This
establishes,
apparently for the first time, a clear link between geometry and
majorizing
measures, and generalizes the earlier results on majorizing measures
on
ellipsoids in Hilbert space, that were obtained by specific methods.
Much
of the rest of the paper is concerned with the structure of bounded
Bernoulli (=Radmacher) processes. The main conjecture on their
structure
is reformulated in several ways, that are shown to be equivalent, and
to be
equivalent to the existence of certain majorizing measures. Two
schemes of
construction of majorizing measures related to this problem are
presented. One allows to describe Bernoulli processes
when the index set, provided with the supremum norm, is sufficiently
small.
The other allows to prove a weak form of the main conjecture. This
result,
while not sufficient to characterize boundedness of Bernoulli
processes,
allows to prove the
remarkable fact that for any continuous operator $T$ from $C(K)$ to
$E$,
the Rademacher cotype-2 constant of $T$ is controlled by the maximum of
the
Gaussian cotype-2 constant of $T$ and of its $(2,1)$-summing norm. It
is
also proved, as a consequence of one of the main inequalities on
Bernoulli
processes, that in a Banach space $E$ of dimension $n$, at most
$n\log n \log\log n$ vectors suffices to compute the Rademacher cotype
$2$ constant of $E$ within a universal constant.

Abstract:Structural properties are given for $D(K)$, the Banach algebra
of
(complex) differences of bounded semi-continuous functons on a metric
space $K$. For example, it is proved that if all finite derived sets of
$K$
are non-empty, then a complex function $\varphi$ operates on $D(K)$
(i.e., $\varphi\circ f\in D(K)$ for all $f\in D(K)$) if and only if
$\varphi$ is locally Lipschitz. Another example: if $W\subset K$ and
$g\in D(W)$ is real-valued, then it is proved that $g$ extends to a
$\tilde g$ in $D(K)$ with $\|\tilde g\|_{D(K)} = \|g\|_{D(W)}$.
Considerable
attention is devoted to $SD(K)$, the closure in $D(K)$ of the set of
simple
functions in $D(K)$. Thus it is proved that every member of $SD(K)$ is
a
(complex) difference of semi-continuous functions in $SD(K)$, and that
$|f|$ belongs to $SD(K)$ if $f$ does. An intrinsic characterization of
$SD(K)$ is given, in terms of transfinite oscillation sets. Using the
transfinite oscillations, alternate proofs are given of the results of
Chaatit, Mascioni and Rosenthal that functions of finite Baire-index
belong
to $SD(K)$, and that $SD(K)\ne D(K)$ for interesting $K$.
It is proved that the ``variable oscillation criterion'' characterizes
functions belonging to $B_{1/4}(K)$, thus answering an open problem
raised
in earlier work of Haydon, Odell and Rosenthal. It is also proved that
$f$
belongs to $B_{1/4}(K)$ (if and) only if $f$ is a uniform limit of
simple
$D$-functions of uniformly bounded $D$-norm iff $\osc_\omega f$ is
bounded;
the last equivalence has also been obtained by V.~Farmaki, using other
methods. Elementary computations of the $D$-norm of some special simple
functions are given; for example the $D$-norm of $\chix_A$ for a given
set $A$ is computed precisely, in terms of $\partial^j A$, the $j$-th
boundary of $A$, $j=1,2,\ldots$. The main structural results on $SD(K)$
and $B_{1/4}(K)$ are obtained using the finite oscillations of a given
function. The higher order oscillations are exploited for the study of
the transfinite analogues of $B_{1/4}(K)$, in subsequent work.

generalized version of M.~Riesz's theorem for conjugate functions with
values in the Banach space is bounded. We use transference to prove
that spaces for which the Hilbert transform is bounded, i\.e\.
$X\in\text{HT}$, are ACF spaces. We then show that Bourgain's proof of
$X\in\text{HT}\implies X\in\text{UMD}$ is a consequence of this
result.

Update: CONFERENCE ON POLYNOMIAL INEQUALITIES
(Sept. 29 - Oct. 1, 1994)
Kent State University, Kent, Ohio 44242.
Dear Colleagues,
It is a few months since some of you have heard from
us about this meeting, and perhaps it is a good idea to give
you the very brief update.
We have been fortunate that a number of excellent
mathematicians have tentatively agreed to participate.
Among them are the following:
Miroslaw Baran
Frank Beaucoup
Bernard Beauzamy
Anne Bellido
Peter Borwein
David Boyd
Jerome Degot
Robert Gardner
Narendra Govil
Larry Harris
William Harris
J.C. Hohl
Maciej Klimek
Norm Levenberg
Miguel Lacruz
Jose Llavona
Yolanda Melendez
R.H. Mohapatra
Wieslaw Plesniak
Bruce Reznick
Yannis Sarantopoulos
Jozef Siciak
Richard Varga
We are hoping to have a small-to-medium sized meeting,
of around 50-60 mathematicians. Thus, on the one hand, resources
may be limited. On the other hand, there is always room for one
or two more excellent people! In addition, we would like to do
what we can to encourage young people to attend, and your help
in bringing them to our attention (and vice versa) would be
appreciated.
Our financial situation is still not absolutely clear,
although things are not completely bleak. In particular, we have
recently been informed that the Institute for Mathematics and its
Applications (I.M.A.) has awarded a grant to this meeting. As a
result, we believe it to be likely that we will be able to pay
for the housing (in a nearby motel) for each of the participants
for all 3 nights of the meeting. We still have several grant
applications pending. As soon as we know the outcome of these
applications, we will be able to inform you about whether we
will be able to provide additional support for everyone,
or whether we will be able to provide travel support for some
participants. Needless to say, if you can help us by using
other grant money to pay for your travel and/or accommodation,
then this would be greatly appreciated, and would free up
resources for others.
We'll be in touch again by the end of the Summer with
further details about the meeting.
With best wishes,
Richard M. Aron and Andrew M. Tonge (for the organizers)

PRELIMINARY ANNOUNCEMENT OF SUMMER TAMIRFAS
The Informal Regional Functional Analysis Seminar
will meet Saturday, August 13 and Sunday, August 14
in 317 Milner Hall at Texas A&M in College Station.
SCHEDULE: TBA. The first talk on Saturday will be at 11 a.m. and
the last talk on Sunday will end at 5 or 6 p.m.
HOUSING: Since this is graduation weekend at A&M, you will
probably have difficulty making reservations directly. We have
reserved some rooms at Day's Inn. You will need to go through Julie
Hodges, (hodges at math.tamu.edu, (409) 845-3261, (409) 845-6028
FaX) to get one of these rooms. Please tell Julie whether you are
requesting support, the type of accomodation you desire (smoking
or nonsmoking), which night(s) you need the room, and give her a
roommate preference.
We expect to be able to cover housing, possibly in a double room,
for most participants. Preference will be given to participants who
do not have other sources of support, such as sponsored research
grants.

several applications.
Amongst them are constructions of a new prime Banach
space, a space isomorphic to its subspaces of codimension two but not
to its hyperplanes and a space isomorphic to its cube but not to its
square.

The first, $X_{u}$, has an unconditional basis and
is arbitrarily distortable. The second, $X$, does not
contain any unconditional basic sequence. Both are
spaces of the type of Tsirelson. We thus answer
a question raised by W.T.Gowers.

HOUSING: Since this is graduation weekend at A&M, you will probably
have difficulty making reservations directly. We have reserved some
rooms at Day's Inn. You will need to go through Julie Hodges,
(hodges at math.tamu.edu, (409) 845-3261, (409) 845-6028 FaX) to get one
of these rooms. Please tell Julie whether you are requesting support,
the
type of accomodation you desire (smoking or nonsmoking), which
night(s)
you need the room, and give her a roommate preference.
We expect to be able to cover housing, possibly in a double room, for
most
participants. Preference will be given to participants who do not have
other sources of support, such as sponsored research grants.

Abstract:Let $X$ be a Banach space with an unconditional
finite-dimensional Schauder decomposition $(E_n)$. We consider the
general problem of characterizing conditions under which one can
construct an unconditional basis for $X$ by forming an unconditional
basis for each $E_n.$ For example, we show that if
$\sup \dim E_n<\infty$ and $X$ has Gordon-Lewis local unconditional
structure then $X$ has an unconditional basis of this type. We also
give an example of a non-Hilbertian space $X$ with the property that
whenever $Y$ is a closed subspace of $X$ with a UFDD $(E_n)$ such that
$\sup\dim E_n<\infty$ then $Y$ has an unconditional basis, showing that
a recent result of Komorowski and Tomczak-Jaegermann cannot be
improved.

4) Calculus III
In our department, the GPA varied from 1.9 to 2.4 out of 4.00 in recent
years. The administrators think that this is low compared
to the GPA in humanities and social sciences.
Any comments on this topic will be appreciated.
Thanks in advance.

Abstract:Let $\msp$ be a measure space and let $1 < p < \infty$. The
{\em weak
$L^p$}\/ space $\wlp$ consists of all measurable functions $f$ such
that
\[ \|f\| = \sup_{t>0}t^{\frac{1}{p}}f^*(t) < \infty,\]
where $f^*$ is the decreasing rearrangement of $|f|$.
It is a Banach space under a norm which is equivalent to the
expression above. In this paper, we pursue the problem of
classifying weak $L^p$ spaces isomorphically when
$\msp$ is purely atomic. It is also shown that if $\msp$ is a
countably generated $\sigma$-finite
measure space, then $\wlp$ (if infinite dimensional) must
be isomorphic to either $\ell^\infty$ or $\seq$.
The results of this article were presented at the conference in
Columbia,
Missouri in May, 1994.

Abstract:For an arbitrary infinite-dimensional Banach space $\X$,
we construct examples of strongly-measurable
$\X$-valued Pettis integrable functions
whose indefinite Pettis integrals are nowhere weakly differentiable;
thus, for these functions the
Lebesgue Differentiation Theorem fails rather spectacularly.
We also relate the degree of nondifferentiability
of the indefinite Pettis integral to the cotype of $\X$, from which
it follows that
our examples are reasonably sharp.
This is an expanded version of a previously posted paper with the same

Abstract:Let $X$ be a (real or complex) rearrangement-in\-va\-riant
function space on $\Om$ (where $\Om = [0,1]$ or $\Om \subseteq \bbN$)
whose norm is not proportional to the $L_2$-norm. Let $H$ be a
separable Hilbert space. We characterize surjective isometries of
$X(H).$ We prove that if $T$ is such an isometry then there exist Borel
maps $a:\Om\to\bbK$ and $\sigma:\Om\lra\Om$ and a strongly measurable
operator map $S$ of $\Om$ into $\calB(H)$ so that for almost all $\om$
$S(\om)$ is a surjective isometry of $H$
and for any $f\in X(H)$ $$Tf(\om)=a(\om)S(\om)(f(\sigma(\om))) \text{
a.e.}$$
As a consequence we obtain a new proof of characterization of
surjective isometries in complex rearrangement-invariant function
spaces.

end
to: banach-files at math.okstate.edu.
Abstract: Let $X$ be a Banach space and $(f_n)_n$ be a
bounded sequence in $L^1(X)$. We prove a complemented
version of the celebrated Talagrand's dichotomy i.e
we show that if $(e_n)_n$
denotes the unit vector basis of $c_0$, there exists a sequence $g_n
\in
\text{conv}(f_n,f_{n+1},\dots)$ such that for almost every $\omega$,
either
the sequence $(g_n(\omega) \otimes e_n)$ is weakly Cauchy in $X
\widehat{\otimes}_\pi c_0$ or it is equivalent to the unit vector basis
of
$\ell^1$. We then get a criterion for a bounded sequence to contain a
subsequence equivalent to a complemented copy of
$\ell^1$ in $L^1(X)$. As an application, we show that for a Banach
space
$X$, the space $L^1(X)$ has
Pe\l czy\'nski's property $(V^*)$ if and only if $X$ does.

Abstract:
Let $E$ be a separable Banach space and $\Omega$ be a compact Hausdorff
space. It is shown that the space $C(\Omega,E)$ has property (V) if and
only if $E$ does. Similar result is also given for Bochner spaces
$L^p(\mu,E)$ if $1<p<\infty$ and $\mu$ is a finite Borel measure on
$\Omega$.

Abstract:Given an operator $T:U_X(\Sigma)\to Y$ or ${T:U(\Sigma)\to Y$,
one may
consider the net of conditional expectation operators $(T_\pi)$
directed by refinement of the partitions $\pi$. It has been shown
previously that $(T_\pi)$ does not always converge to $T$. This paper
gives several conditions under which this convergence does occur,
including complete characterizations when $X={\bold R}$ or when $X\sp
*$ has the Radon-Nikod\'ym property.

It appears that the warning message that I forwarded was part of a
hoax. Below is an advisory about Good Times.

THE "Good Times" VIRUS IS AN URBAN LEGEND
In the early part of December, CIAC started to receive information
requests
about a supposed "virus" which could be contracted via America OnLine,
simply
by reading a message. The following is the message that CIAC
received:
---------------------------------------------------------------------------
| Here is some important information. Beware of a file called
Goodtimes. |
|
|
| Happy Chanukah everyone, and be careful out there. There is a virus
on |
| America Online being sent by E-Mail. If you get anything called
"Good |
| Times", DON'T read it or download it. It is a virus that will erase
your |
| hard drive. Forward this to all your friends. It may help them a
lot. |
---------------------------------------------------------------------------
THIS IS A HOAX. Upon investigation, CIAC has determined that this
message
originated from both a user of America Online and a student at a
university
at approximately the same time, and it was meant to be a hoax.
CIAC has also seen other variations of this hoax, the main one is that
any
electronic mail message with the subject line of "xxx-1" will infect
your
computer.
This rumor has been spreading very widely. This spread is due mainly
to the
fact that many people have seen a message with "Good Times" in the
header.
They delete the message without reading it, thus believing that they
have
saved themselves from being attacked. These first-hand reports give a
false
sense of credibility to the alert message.
There has been one confirmation of a person who received a message with
"xxx-1" in the header, but an empty message body. Then, (in a panic,
because
he had heard the alert), he checked his PC for viruses (the first time
he
checked his machine in months) and found a pre-existing virus on his
machine.
He incorrectly came to the conclusion that the E-mail message gave him
the
virus (this particular virus could NOT POSSIBLY have spread via an
E-mail
message). This person then spread his alert.
As of this date, there are no known viruses which can infect merely
through
reading a mail message. For a virus to spread some program must be
executed.
Reading a mail message does not execute the mail message. Yes, Trojans
have
been found as executable attachments to mail messages, the most
notorious
being the IBM VM Christmas Card Trojan of 1987, also the TERM MODULE
Worm
(reference CIAC Bulletin B-7) and the GAME2 MODULE Worm (CIAC Bulletin
B-12).
But this is not the case for this particular "virus" alert.
If you encounter this message being distributed on any mailing lists,
simply
ignore it or send a follow-up message stating that this is a false
rumor.

$\ell^p_2 \otimes_{\p} \ell^q_2$" by P. Bandyopadhyay and A.K. Roy.

Abstract:In this paper, we show that the projective tensor product of a
two-dimen\-sional $\ell^p$ space with a two-dimensional $\ell^q$
space never has the Mazur Intersection Property for a large
range of values of $p$ and $q$. For this purpose, we
characterise the extreme contractions from $\ell^p_2$ to
$\ell^q_2$ and obtain their closure.

Abstract:Let $T\dopu C(S)\to C(S)$ be a bounded linear operator. We
present a
necessary and sufficient condition for the so-called Daugavet equation
$$ \|\Id+T\| = 1+\|T\| $$ to hold, and we apply it to weakly compact
operators and to operators factoring through $c_{0}$. Thus we obtain
very simple proofs of results by Foias, Singer, Pelczynski, Holub and
others.

We also compute the operator norm of the

function over rectangles on $L^p(\Bbb R^n)$, and we show that
the operator norm of the uncentered Hardy-Littlewood maximal
function over balls on $L^p(\Bbb R^n)$ grows exponentially
with the dimension as $n \rightarrow \infty$.

Abstract:Orlicz--Lorentz spaces provide a common generalization of
Orlicz spaces and Lorentz spaces. In this paper, we investigate their
Boyd indices. Bounds on the Boyd indices in terms of the
Matuszewska--Orlicz indices of the defining functions are given. Also,
we give an example to show that the Boyd indices and Zippin indices of
an Orlicz--Lorentz space need not be equal, answering a question of
Maligranda. Finally, we show how the Boyd indices are related to
whether an Orlicz--Lorentz space is $p$-convex or $q$-concave.

Abstract:For any complex Banach space $X$, let $J$ denote the duality
mapping
of $X$. For any unit vector $x$ in $X$ and
any ($C_0$) contraction semigroup $(T_t)_{t>0}$ on $X$, Baillon and
Guerre-Delabriere proved that if $X$ is a smooth reflexive Banach space
and if there is $x^* \in J(x)$ such that $|\langle T(t) \,
x,J(x)\rangle| \to 1 $ as $t \to \infty$, then there is a unit vector
$y\in X$ which is an eigenvector of the generator $A$ of $(T_t)_{t>0}$
associated with a purely imaginary eigenvalue. They asked whether this
result is still true if $X$ is replaced by $c_o$. In this article, we
show the answer is negative.

Abstract:K.\ S.\ Lau had shown that a reflexive Banach space has the
Mazur Intersection Property (MIP) if and only if every closed
bounded convex set is the closed convex hull of its farthest
points.
In this work, we show that in general this latter property is
equivalent to a property stronger than the MIP. As corollaries,
we recapture the result of Lau and characterize the w*-MIP in
dual of RNP spaces.
