This is the abstract of the paper "The Pelczynski property for tight
subspaces" by S. Saccone. The paper is typed in Plain TeX. The paper may
be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or
transmitting the command

Abstract:We show that if X is a tight subspace of C(K) then X has the
Pelczynski property and X^* is weakly sequentially complete. We apply
this result to the space U of uniformly convergent Taylor series on the
unit circle and using a minimal amount of Fourier theory prove a
theorem of Bourgain, namely that U has the Pelczynski property and U^*
is weakly sequentially complete. Using separate methods, we prove U and
U^* have the Dunford-Pettis property. Some results concerning pointwise
bounded approximation are proved for tight uniform algebras. We use
tightness and the Pelczynski property sto make a remark about inner
functions on strictly pseudoconvex domains in C^n.

This is the abstract of the paper "Metric entropy of homogeneous spaces

Abstract:For a (compact) subset $K$ of a metric space and $\varepsilon
> 0$, the {\em covering number} $N(K , \varepsilon )$ is defined as
the smallest number of balls of radius $\varepsilon$ whose union covers
$K$. Knowledge of the {\em metric entropy}, i.e., the asymptotic
behaviour of covering numbers for (families of) metric spaces is
important in many areas of mathematics (geometry, functional analysis,
probability, coding theory, to name a few). In this paper we give
asymptotically correct estimates for covering numbers for a large class
of homogeneous spaces of unitary (or orthogonal) groups with respect to
some natural metrics, most notably the one induced by the operator
norm. This generalizes earlier author's results concerning covering
numbers of Grassmann manifolds; the generalization is motivated by
applications to noncommutative probability and operator algebras. In
the process we give a characterization of geodesics in $U(n)$ (or
$SO(m)$) for a class of non-Riemannian metric structures.

Abstract:It is proved that, for each pair (m,n) of non-negative
integers, there is a Banach space X for which the group K_0(B(X)) is
isomorphic to m copies of the integers and the group K_1(B(X)) is
isomorphic to n copies of the integers. Along the way we compute the
K-groups of all closed ideals of operators contained in the ideal of
strictly singular operators, and we derive some results about the
existence of splittings of certain short exact sequences.

Abstract:An old problem of P. Levy is to characterize those Banach
spaces which embed isometrically in $L_p.$ We show a new criterion in
terms of the second derivative of the norm. As an application, we show
that if $M$ is a twice differentiable Orlicz function with
$M'(0)=M''(0)=0$ then the $n$-dimensional Orlicz space $\ell_M^n,\ n\ge
3,$ does not embed isometrically in $L_p$ with $0<p\le 2.$ These
results generalize and clear up the recent solution to the 1938
Schoenberg's problem on positive definite functions.

Abstract:In this paper we give some results about the approximation of

functions. In particular, we prove that the density of $\Delta$-convex
functions in the set of Lipschitz functions for the topology of uniform
convergence on bounded sets characterizes the superreflexivity of the
Banach space. We also show that Lipschitz functions on superreflexive
Banach spaces are uniform limits on the whole space of $\Delta$-convex
functions.

algebras are shown to be a bounded linear map from $L^p(M,t)$ into
$L^p(M,t)$ for $1<p<\infty$, and to be a continuous linear map from
$L^1(M,t)$ into $L^{1,\infty}(M,t)$. We also obtain that if a positive
operator $a$ is such that $a\log^{+}a \in L^1(M,t)$, then its conjugate
belongs to $L^1(M,t)$.

Abstract:Let $A$ be a $C^*$-algebra. It is shown that every absolutely
summing operator from $A$ into $\ell_2$ factors through a Hilbert
space operator that belongs to the 4-Schatten- von Neumann class. We
also provide finite dimensinal examples that show that one can not
improve the 4-Schatten-von Neumann class to $p$-Schatten von Neumann
class for any $p<4$. As application, we prove that there exists a
modulus of capacity $\epsilon \to N(\epsilon)$ so that if $A$ is a
$C^*$-algebra and $T \in \Pi_1(A,\ell_2)$ with $\pi_1(T)\leq 1$, then
for every $\epsilon >0$, the $\epsilon$-capacity of the image of the
unit ball of $A$ under $T$ does not exceed $N(\epsilon)$. This aswers
positively a question raised by Pe\l czynski.

integral theory in $L^2$, developed by Barnett, Streater and Wilde, to
$L^p$ for all $1<p<\infty$. We include an appendix on the
non-commutative analogue of the classical Fefferman duality between
$H^1$ and $BMO$.

Abstract:In analogy with the maximal tensor product of
$C^*$-algebras, we define the ``maximal" tensor product $E_1\otimes_\mu
E_2$ of two operator spaces $E_1$ and $E_2$ and we show that it can be
identified completely isometrically with the sum of the two Haagerup
tensor products: \ $E_1\otimes_h E_2 + E_2\otimes_h E_1$. Let $E$ be an
$n$-dimensional operator space. As an application, we show that the
equality $E^* \otimes_\mu E=E^* \otimes_{\rm min} E$ holds
isometrically iff $E = R_n$ or $E=C_n$ (the row or column
$n$-dimensional Hilbert spaces). Moreover, we show that if an operator
space $E$ is such that, for any operator space $F$, we have
$F\otimes_{\min} E=F\otimes_{\mu} E$ isomorphically, then $E$ is
completely isomorphic to either a row or a column Hilbert space.

Abstract:Let $u(x,t)$ be the solution of the Schr\"odinger or wave
equation with $L_2$ initial data. We provide counterexamples to
plausible conjectures involving the decay in $t$ of the $\BMO$ norm of
$u(t,\cdot)$. The proofs make use of random methods, in particular,
Brownian motion.
Despite the applied sounding title, this really is a paper in harmonic
analysis.

Abstract:The best constant in the usual $L^p$ norm inequality for the
Hardy-Littlewood maximal function on $\Bbb R^1$ is obtained for the
class of all ``bell-shaped'' functions. A positive function on the
line is called ``bell-shaped'' if it is smooth and has only one hump.
The techniques we use include convexity and an adaptation of the
standard Euler-Langrange variational method.

\centerline{\bf G\^ateaux Differentiability of Convex Functions and Topology --}
\centerline{\bf Weak Asplund Spaces}
\bigskip
\centerline{by}
\bigskip
\centerline{\it Mari\'an Fabian}
\bigskip
This book deals with the G\^ateaux differentiability of convex functions
and its relationship to the
structure of Banach spaces. In particular, Banach spaces,
for which every convex continuous function
is G\^ateaux differentiable at the points of
a $G_{\delta}$ dense subset -- called weak Asplund spaces --
are investigated here. In the first chapter
examples
of such spaces -- Asplund (generated)
spaces and weakly compactly generated spaces,
and their topological counterparts -- Radon-Nikod\'ym and Eberlein
compacta are studied. In Chapter two we discuss
properties of the weak Asplund spaces.
The largest subclass of the weak Asplund
spaces, and their topological counterpart
- -- Stegall's classes are --
studied in the next chapter.
In Chapter 4 we will show that weakly $\cal K$-analytic and G\^ateaux
smooth spaces
are weak Asplund spaces.
The next chapter is devoted to the study
of fragmentable topological spaces and its relationship to
weak Asplundness and Stegall's class.
Chapter 6 deals with the so called projectional resolutions of the identity.
This powerful tool is then used in the last two chapters.
In chapter 7 a theory of Va\v s\'ak (i.e. weakly countably determined) spaces
is built together with its topological counterpart -- Gu'lko
compacta.
In the last chapter a relationship between
Va\v s\'ak, weakly Lindel\"of determined,
weakly compactly generated and Asplund spaces is studied.
A topological counterpart is also discussed there, namely a connection between
Talagrand, Gul'ko, Corson,
Radon-Nikod\'ym, and Eberlein compacta.
The book contains several counterexamples, due to
Talagrand, Rezni\v cenko, Argyros, etc placing the weak Asplund spaces
among other important classes of nonseparable Banach spaces.
Each chapter is completed by an exhaustive "Notes and remarks" section.
The book ends with the discussion on the main open problems
in the
theory of the weak Asplund spaces. A list of references contains about 150
papers and books.
The text is addressed to all graduate students and
researchers working in Banach spaces and
topology who want to study
the topic of generic G\^ateaux
differentiability of convex functions and its relationship to
the structure of Banach spaces..

This is the abstract of the paper "Modified mixed Tsirelson spaces" by

Abstract:We study the modified and boundedly modified mixed Tsirelson
spaces $T_M[({\cal F}_{k_n},\theta_n)_{n=1}^{\infty }]$ and
$T_{M(s)}[({\cal F}_{k_n},\theta_n)_{n=1}^{\infty }]$ respectively,
defined by a subsequence $({\cal F}_{k_n})$ of the sequence of Schreier
families $({\cal F}_n)$. These are reflexive asymptotic $\ell_1$ spaces
with an unconditio- nal basis $(e_i)_i$ having the property that every
sequence $\{ x_i\}_{i=1}^n$ of normalized disjointly supported vectors
contained in $\langle e_i\rangle_{i=n}^{\infty }$ is equivalent to the
basis of $\ell_1^n$. We show that if $\lim\theta_n^{1/n}=1$ then the
space $T[({\cal F}_n,\theta_n) _{n=1}^{\infty }]$ and its modified
variations are totally incomparable by proving that $c_0$ is finitely
disjointly representable in every block subspace of $T[({\cal F}_n,
\theta_n)_{n=1}^{\infty }]$. Next, we present an example of a boundedly
modified mixed Tsirelson space $X_{M(1),u}$ which is arbitrarily
distortable. Finally, we construct a variation of the space
$X_{M(1),u}$ which is hereditarily indecomposable.

Abstract:Let $A$ be a unital operator algebra. Let us assume that
every {\it bounded\/} unital homomorphism $u\colon \ A\to B(H)$ is
similar to a {\it contractive\/} one.
Let $\text{\rm Sim}(u) = \inf\{\|S\|\, \|S^{-1}\|\}$ where the infimum
runs over all invertible operators $S\colon \ H\to H$ such that the
``conjugate'' homomorphism $a\to S^{-1}u(a)S$ is contractive. Now for
all $c>1$, let $\Phi(c) = \sup\text{\rm Sim}(u)$ where the supremum
runs over all unital homomorphism $u\colon\ A\to B(H)$ with $\|u\|\le
c$.
Then, there is $\alpha\ge 0$ such that for some constant $K$ we
have: $$\Phi(c) \le Kc^\alpha.\leqno (*)\qquad \forall c>1$$ Moreover,
the smallest $\alpha$ for which this holds is an integer, denoted by
$d(A)$ (called the similarity degree of $A$) and $(*)$ still holds for
some $K$ when $\alpha=d(A)$. Among the applications of these
results, we give new characterizations of proper uniform algebras on
one hand, and of nuclear $C^*$-algebras on the other. Moreover, we
obtain a characterization of amenable groups which answers (at least
partially) a question on group representations going back to a 1950
paper of Dixmier.

Furthermore, we prove that in the case of extensions of C(H) by

reflexive. Concerning the most well-known extensions of C(H) by the
algebra of all continuous complex valued functions on the perimeter of
the unit disc, we show that the automorphism and isometry groups are
topologically nonreflexive.

Abstract:We present here a new method for approximating functions
defined on superreflexive Banach spaces by differentiable functions
with $\alpha$-H\"older derivatives (for some $0<\alpha\leq 1$). The
smooth approximation is given by means of an explicit formula enjoying
good properties from the minimization point of view. For instance, for
any function $f$ which is bounded below and uniformly continuous on
bounded sets this formula gives a sequence of $\Delta$-convex
${\Cal{C}}^{1,\alpha}$ functions converging uniformly on bounded sets
to $f$ and preserving the infimum and the set of minimizers of $f$.
The techniques we develop are based on the use of {\sl extended
inf-convolution} formulas and convexity properties such as the
preservation of smoothness for the convex envelope of certain
differentiable functions.

This is the abstract of the paper "Metric unconditionality and Fourier
analysis" by S. Neuwirth. The paper is typed in LaTeX2.09. The paper
may be downloaded from the bulletin board by ftp to

Abstract:We investigate several aspects of almost
$1$-unconditionality. We characterize the metric unconditional
approximation property UMAP in terms of ``block unconditionality''.
Then we focus on translation invariant subspaces $L^p_E(T)$ and
$C_E(T)$ of functions on the circle and express block unconditionality
as arithmetical conditions on $E$. Our work shows that the spaces
$L^p_E(T)$, $p$ an even integer, have a singular behaviour from the
almost isometric point of view: property UMAP does not interpolate
between spaces $L^p_E(T)$ and $L^{p+2}_E(T)$. These arithmetical
conditions are used to construct counterexamples for several natural
questions and to investigate the maximal density of such sets $E$. We
also prove that if $E=\{n_k\}_{k\ge1}$ with $|n_{k+1}/n_k|\to\infty$,
then $C_E(T)$ has UMAP and we get a sharp estimate of the Sidon
constant of Hadamard sets. Finally, we investigate the relationship of
metric unconditionality and probability theory.

TO ALL MATHEMATICIANS WHO HAVE PRELIMINARILY PREREGISTERED FOR
THE INTERNATIONAL CONGRESS OF MATHEMATICIANS 1998 IN BERLIN
Fifteenth Circular Letter, August 18, 1997
Subject ICM98-CL15: First Announcement
Dear colleague:
Imagine, at this moment in exactly one year, you are sitting
in the great lecture hall of the International Congress Center
in Berlin and you are watching the Opening Ceremony of ICM'98
progress. You will be
- listening to words of welcome from the IMU President,
the President and the Honorary President of the ICM'98
Organizing Committee,
- hearing greetings by a representative of the President of
the Federal Republic of Germany (who is the protector of
the Congress), and welcome speeches of the Federal Minister
of Science and Technology and the Governing Mayor of Berlin
(the two most important financial sponsors of ICM'98),
- watching a short movie about Berlin, getting a glimpse of
the VideoMath Festival, and listening to music interludes,
- and, finally, you will be seeing the winners of the Fields
Medals and the Nevanlinna Prize enter the stage.
A modern version of Grimm's "Tischlein deck dich" will link
this event to the afternoon session with the laudationes on
the prize winners and a Plenary Lecture delivered by one of
the leading mathematicians of the world.
Wouldn't you want to tell your friends and colleagues about
this event?
There has been a long tradition that the organizers of an
International Congress send out a so-called First Announcement
to as many mathematicians as possible about one year before
the Congress. We are following this tradition.
The main aim of the First Announcement is to collect the addresses of
those mathematicians who are seriously interested in participating in
ICM'98. These are asked to request the Second Announcement in the way
described in the First Announcement (below). The Second Announcement
will contain all the details about ICM'98 that you would like to know.
(These can, of course, also be found on the ICM'98 server.) Those
who provide an e-mail address with their request will also receive
the circular letters from the ICM'98 e-mail service.
IMPORTANT:
==========
The persons who have submitted the request form for the
Second Announcement (AND ONLY THESE) will receive the Second
Announcement in January 1998 by ordinary mail.
FOR YOUR CONVENIENCE:
====================
If you have preliminarily preregistered for ICM'98 before (this is the
case if you obtained the present circular letter from the ICM'98 E-Mail
Server) you should not do anything at present. You will automatically
receive a personal e-mail request form for the Second Announcement
within the next week. This way you can check the data we have in our
data base and you may correct your mailing address if necessary. If you
have not received the request form by August 26, 1997 something went
wrong and we have to ask you to follow the procedure described in the
First Announcement.
With this First Announcement we try to reach, in particular, those
mathematicians who are not yet using electronic media intensively. We
have therefore asked all Mathematical Societies in the world (that we
know of), all Adhering Organizations of IMU and all National Committees
of Mathematics to distribute the First Announcement by mail or through
their newsletters. We are grateful for the support of many of these
institutions but quite a number did not react, unfortunately.
That is why we ask you for support.
- Could you please forward this First Announcement to your friends and
colleagues who might be interested in ICM'98?
- If you have relations to a Mathematical Society, please ask the editor
in charge of the newsletter to print the First Announcement in the
next issue.
- Print the First Announcement and post it in your institute.
To make all this easy for you, we have produced a simple two-page
First Announcement without any fancy graphics etc. We provide it in
various versions.
Below you will find the ASCII version suitable for e-mail distribution.
If you call the URL
http://elib.zib.de/ICM98/First_Announcement
you will find
- three postscript versions (two pages) of size about 300 Kb each
- with color ICM'98 logo,
- with grey-scale ICM'98 logo,
- with black-white ICM'98 logo,
- a LATEX version (without ICM'98 Logo)
- three WORD versions (two pages) of size about 170 Kb each
- with color ICM'98 logo,
- with grey-scale ICM'98 logo,
- with black-white ICM'98 logo,
- the ASCII version,
- and the corresponding logos in postscript format of size about 94 Kb.
You should be able to print one of these on your printer.
It is also possible to obtain the files by anonymous ftp from elib.zib.de
in the subdirectory pub/IMU/HTML/ICM98/First_Announcement.
The files of interest are
anc_col.ps Announcement Postscript color

If you want to help us by mailing First Announcements to some of
your colleagues we are also ready to mail any (reasonable) number of
printed Announcements to you. Just send me an e-mail with your mailing
address and the requested number of First Announcements.
Thanks for your help!

First Announcement
_________________________________________________________________
The Organizing Committee is pleased to announce that the next
International Congress of Mathematicians will take place in Berlin,
Germany, from Tuesday, August 18, through Thursday, August 27, 1998.
It will be held under the auspices of the International
Mathematical Union (IMU) and sponsored by many other institutions.
-----------------------------------------------------------------
Mathematical Program
-----------------------------------------------------------------
Responsibility for the scientific program lies with the Program
Committee appointed by IMU. There will be about twenty one-hour
Plenary Lectures covering recent developments in the major areas
of mathematics and about 170 forty-five-minute Invited Lectures
in nineteen sections. The sections are as follows:
1. Logic
2. Algebra
3. Number Theory and Arithmetic Algebraic Geometry
4. Algebraic Geometry
5. Differential Geometry and Global Analysis
6. Topology
7. Lie Groups and Lie Algebras
8. Analysis
9. Ordinary Differential Equations and Dynamical Systems
10. Partial Differential Equations
11. Mathematical Physics
12. Probability and Statistics
13. Combinatorics
14. Mathematical Aspects of Computer Science
15. Numerical Analysis and Scientific Computing
16. Applications
17. Control Theory and Optimization
18. Teaching and Popularization of Mathematics
19. History of Mathematics
Every registered participant (traditionally called Ordinary
Member) of the Congress will have the opportunity to give a short
presentation, either during a poster session or in the form
of a fifteen-minute lecture. A formal call for such presentations
will be issued in the Second Announcement. Informal mathematical
seminars may be organized at the initiative of groups of
participants. English, French, German, and Russian are
the official languages of the Congress.
All Plenary and Invited Lectures will be published in the
Proceedings of ICM'98; after the Congress, a complimentary copy
of these Proceedings will be sent to each Ordinary Member.
Abstracts of all lectures and of all short presentations will
be distributed free of charge to Ordinary Members at Congress
check-in.
The Fields Medals and the Nevanlinna Prize will be awarded
during the Opening Ceremony on the first day of the Congress.
This will take place in the International Congress Center
Berlin (ICC); all other scientific events will be held at
Technische Universitaet Berlin. No scientific activities
are scheduled for Sunday, August 23.
In an effort to reach out to a wider audience, the ICM'98
organizers have initiated several cultural activities related
to mathematics that are attractive to the general public.
In particular, there will be a VideoMath Festival, software
demonstrations, talks about mathematics and its relations to
other subjects, several exhibitions (`Mathematics in the Arts',
etc.), and other events (`Mathematics and Music', etc.).
Special consideration will be given to the impact of the Nazi
regime on mathematics in Berlin and Germany.
-----------------------------------------------------------------
Social Events
-----------------------------------------------------------------
On August 18, a buffet-banquet for all registered participants
will be held at noon directly after the Opening Ceremony in the
ICC. During the Congress, a number of guided tours of Berlin,
visits to museums, and walking tours will be offered. On Sunday,
August 23, it will be possible to choose from several excursions.
For that evening, tickets have been reserved for the opera
`The Magic Flute' at the Deutsche Oper. Registered participants
may purchase tickets in advance for these events as well as for
many day trips and pre- or post-congress tours to places of
interest in the vicinity of Berlin.

Registration and Accommodation
----------------------------------------------------------------------
DER-CONGRESS, a professional congress and tour organizer, has been
appointed by the Organizing Committee to handle all non-scientific
matters for individual participants: registration to the Congress
and the social events, hotel reservation, tourist program, collection
of registration fees, etc. The formal registration procedure for the
Congress will be described in the Second Announcement (see below).
Participants will be housed in a variety of hotels in Berlin;
the necessary reservations have already been made by DER-CONGRESS.
In addition, DER-CONGRESS will make student residences available
and will provide a certain amount of private accommodation at a
cheap rate for participants willing to accept less comfort.
Detailed information on locations and rates will be provided
in the Second Announcement.
Forms for registration and accommodation requests will be
made available on the ICM'98 server in January 1998.
-----------------------------------------------------------------------
Second Announcement
-----------------------------------------------------------------------
The Second Announcement of ICM'98 will describe the activities
of the Congress in more detail and give instructions on how to
complete the registration process and obtain accommodation.
It will provide more, although not complete, information on the
scientific program, contain a call for contributed short presentations,
and give instructions regarding the submission of abstracts.
The Second Announcement will also include advice on how to proceed upon
arrival at airports and train stations, and it will be accompanied by a
brochure describing the day trips and tours organized by DER-CONGRESS.
Several conferences of a more specialized nature are scheduled
immediately before or after ICM'98. The Second Announcement
will also contain a list of such `satellite conferences'.
To receive the Second Announcement, fill out the form on the ICM'98
server (http://elib.zib.de/ICM98). Alternatively, send an empty e-mail
to icm98 at zib.de with `Second Announcement' in the `SUBJECT' line

This is the abstract of the paper "On an inequality of A.~Grothendieck
concerning operators on $L^1$" by H. Rosenthal. The paper is typed in

Abstract:In 1955, A.~Grothendieck proved a basic inequality which
shows that any bounded linear operator between $L^1(\mu)$-spaces maps
(Lebesgue-) dominated sequences to dominated sequences. An elementary
proof of this inequality is obtained via a new decomposition principle
for the lattice of measurable functions. An exposition is also given
of the M.~L\'evy extension theorem for operators defined on subspaces
of $L^1(\mu)$-spaces.

Abstract:Suppose $\Cal J$ is a two-sided quasi-Banach ideal of
compact operators on a separable infinite-dimensional Hilbert
space $\Cal H$. We show that an operator $T\in\Cal J$ can be
expressed as finite linear combination of commutators $[A,B]$
where $A\in\Cal J$ and $B\in\Cal B(\Cal H)$ if and only its
eigenvalues $(\lambda_n)$ (arranged in decreasing order of absolute
value, repeated according to algebraic multiplicity and augmented by
zeros if necessary) satisfy the condition that the
diagonal operator $\diag\{\frac1n(\lambda_1+\cdots +\lambda_n)\}$ is
a member of $\Cal J.$ This answers (for quasi-Banach ideals) a
question raised by Dykema, Figiel, Weiss and Wodzicki.

Abstract:The main object of the paper is to study the distance
between Banach spaces introduced by Kadets. For Banach spaces $X$
and $Y$, the Kadets distance is defined to be the infimum of the
Hausdorff distance $d(B_X,B_Y)$ between the respective closed unit
balls over all isometric linear embeddings of $X$ and $Y$ into a
common Banach space $Z.$ This is compared with the Gromov-Hausdorff
distance which is defined to be the infimum of $d(B_X,B_Y)$ over all
isometric embeddings into a common metric space $Z$. We prove
continuity type results for the Kadets distance including a result
that shows that this notion of distance has applications to
the theory of complex interpolation.

Abstract:We study connections between the problem of the existence of
positive solutions for certain nonlinear equations and weighted
norm inequalities. In particular, we obtain explicit criteria
for the solvability of the Dirichlet problem $$\aligned -& \Delta u
= v \, u^q + w, \quad u \ge 0 \quad \text {on} \quad \Omega, \\ &u =
0 \quad \text {on} \quad \partial \Omega, \endaligned $$ on a
regular domain $\Omega$ in $\bold R^n$ in the ``superlinear case'' $q >
1$. The coefficients $v, w$ are arbitrary positive measurable
functions (or measures) on $\Omega$. We also consider more general
nonlinear differential and integral equations, and study the
spaces of coefficients and solutions naturally associated with these
problems, as well as the corresponding capacities.
Our characterizations of the existence of positive solutions take into
account the interplay between $v$, $w$, and the corresponding
Green's kernel. They are not only sufficient, but also necessary, and
are established without any a priori regularity assumptions on $v$ and
$w$; we also obtain sharp two-sided estimates of solutions up to the
boundary. Some of our results are new even if $v \equiv 1$ and
$\Omega$ is a ball or half-space.
The corresponding weighted norm inequalities are proved for integral
operators with kernels satisfying a refined version of the
so-called $3 G$-inequality by an elementary ``integration by
parts'' argument. This also gives a new unified proof for some
classical inequalities including the Carleson measure theorem for
Poisson integrals and trace inequalities for Riesz potentials and Green
potentials.

geometric stability is necessary for the canonical spectral

This answers a question raised by Dykema, Figiel, Weiss and
Wodzicki. There are some ideals, $\Jc$, having quasi--nilpotent
elements that are not sums of
$(\Jc,B(\Hil))$--commutators. Also, every trace on every
geometrically stable ideal is a spectral trace.

complemented in $L_p$ if and only if $Y$ is; moreover the constants of
complementation of $X$ and $Y$ are equal. We provide examples
demonstrating that this fact fails when $p$ is an even integer larger
than 2.

Non-commutative Poisson transforms are used to provide new von Neumann
type inequalities. Completely isometric representations of the
quotient algebra $F^\infty/J$ on Hilbert spaces, where $J$ is any
$w^*$-closed, 2-sided ideal of $F^\infty$, are obtained and used to
construct a $w^*$-continuous, $F^\infty/J$--functional calculus
associated to row contractions $T=[T_1,\dots, T_n]$ when
$f(T_1,\dots,T_n)=0$ for any $f\in J$. Other properties of the dual

Abstract:A Banach space $X$ is said to have the Daugavet property if
every
operator $T: X\to X$ of rank~$1$ satisfies $\|Id+T\| = 1+\|T\|$. We
show that then every weakly compact operator satisfies this equation
as well and that $X$ contains a copy of $\ell_{1}$. However, $X$ need
not contain a copy of $L_{1}$. We also study pairs of spaces
$X\subset Y$ and operators $T: X\to Y$ satisfying $\|J+T\|=1+\|T\|$,
where $J: X\to Y$ is the natural embedding. This leads to the result
that a Banach space with the Daugavet property does not embed into a
space with an unconditional basis. In another direction, we
investigate spaces where the set of operators with
$\|Id+T\|=1+\|T\|$ is as small as possible and give
characterisations in terms of a smoothness condition.

"CAREER AWARDING IN GREECE TO GREEK-SPEAKING RESEARCHERS
LIVING ABROAD" PROGRAMME
September 24, 1997
Dear Colleague:
The Analysis and Logic group at the Department of Mathematics of the
University of Crete, Greece, is seeking candidates for a 3-4 year
research position funded jointly by the General Secretariat of
Research and Technology (GSRT) and the European Union. Funding is
confirmed only after the candidate's name is specified, hence
we are looking for an exceptionally good person in order to strengthen the
chances of success of our application to the GSRT
(the announcement of the GSRT itself follows at the end of this message).
The candidates should
* be able to speak Greek
* reside currently outside Greece
* work in the general area of Analysis or Logic (this should be
interpreted broadly)
* have a minimum of two years of postdoctoral experience.
There are no teaching requirements and the salary is slightly less
than that of an Assistant Professor. Funding for supporting
one graduate student will also be available. In very exceptional
cases we might consider hiring a more senior person (at a higher salary).
The succesful candidate will be able to conduct independent research
in one of the most dynamic universities in Greece, located on
the beautiful island of Crete. Although the department is
relatively new (20 years old) it has been succesful in sustaining
significant research activity (weekly seminars, graduate program,
organizing several conferences, and a steady stream
of visitors throughout the year), maintaining a good library
and computational facilities.
In the School of Sciences there is also a very good Physics department
as well as departments of Chemistry, Biology and Computer Science.
Our department has close to 30 faculty members.
The deadline for submitting the proposal to the GSRT is November 10, 1997,
and our Department requires that all candidates notify us before
October 25, 1997. Arrange for three (3) letters of recommendation,
an up-to-date CV and any supporting material to arrive by that date (25/10)
at the address:
Prof. Souzana Papadopoulou,
Analysis and Logic Group,
Department of Mathematics,
University of Crete,
714 09 Iraklio, Crete,
GREECE
E-mail (souzana at math.uch.gr) and FAX (+30-81-234516) are preferred
because of the tight timing.
Address all questions to Prof Papadopoulou or myself (kolount at math.uch.gr).

"CAREER AWARDING IN GREECE TO GREEK-SPEAKING RESEARCHERS
LIVING ABROAD" PROGRAMME
November 4, 1997
Dear Colleague:
The Analysis Section of the Department of Mathematics of the
University of Athens, Greece, is seeking candidates for a 3-4 year
research position funded jointly by the General Secretariat of
Research and Technology (GSRT) and the European Union. Funding is
confirmed only after the candidate's name is specified, hence
we are looking for an exceptionally good person in order to
strengthen the
chances of success of our application to the GSRT
(the announcement of the GSRT itself follows at the end of this
message).
The candidates should
* be able to speak Greek
* reside currently outside Greece
* work in the general area of Pure or Applied Analysis (this should
be
interpreted broadly)
* have a minimum of two years of postdoctoral experience
(this should be interpreted broadly).
There are no teaching requirements and the salary is slightly less
than that of an Assistant Professor. Funding for supporting
one graduate student will also be available. In very exceptional
cases we might consider hiring a more senior person (at a higher
salary).
The deadline for submitting the proposal to the GSRT is November 28,
1997,
and our Department requires that all candidates notify us before
November 20, 1997. Arrange for an up-to-date CV, a brief research
proposal and any supporting material to arrive by that date (20/11)
at the address:
Prof. Leonidas Tsitsas,
Department of Mathematics,
University of Athens,
157 84 Athens,
GREECE
E-mail : akatavol at eudoxos.uoa.gr
ldalla at eudoxos.uoa.gr
FAX (+30-1-7243502)
are preferred because of the tight timing.

Abstracts:
Michael Lacey, Georgia Tech.
On the role of Carleson's Theorem in Analysis
Lennart Carleson's theorem of 1965 asserts that the Fourier
series of a square integrable function converges pointwise. The theorem
requires sophisticated methods of decomposition of functions in ways that
are sensitive to time and frequency behavior. I will describe those
aspects of harmonic analysis that are known to be related to Carleson's
Theorem, and expose elements of a new proof of Carleson's Theorem. Much
of the material of this lecture is joint work with Christoph Thiele.
Alan McIntosh, Macquarie University, Sydney and
University of Missouri, Columbia.
Spectral Theory and Harmonic Analysis
I shall explore some connections between harmonic analysis and
the spectral theory of operators in Banach spaces, such as the
relationship between quadratic estimates and the boundedness of
a holomorphic functional calculus.

This is the abstract of the paper "A pair of optimal inequalities
related to the error function" by M. B. Ruskai and E. Werner. The
paper is typed in LaTeX2e. The paper may be downloaded from the
bulletin board by ftp to ftp.math.okstate.edu or transmitting the
command

to: majordomo at littlewood.math.okstate.edu.
Abstract:The Error Function \begin{eqnarray} V(x) & \equiv &
\sqrt{\pi} e^{x^2} [1 - \hbox{erf}(x)] \\ & = & \int_0^\infty \frac{
e^{-u} }{\sqrt{x^2 + u}} du = 2 e^{x^2}\int_x^\infty e^{-t^2} dt
\nonumber \end{eqnarray} arises in many contexts, from probability to
mathematical physics. We give estimates for the Error Function from
above and below which are optimal within a certain class of functions.

Abstract:Lipschitz quotient mappings and uniform quotient mappings
between Banach spaces are introduced and investigated. In particular,
it is shown that if a Banach space is a uniform quotient of $L_p$,
$1<p<\infty$, then it is isomorphic to a linear quotient of $L_p$. For
the purpose of studying quotient mappings and also for their own
interest, new concepts related to approximating general Lipschitz
functions by affine functions are introduced and characterized.

Abstract:It is shown that every Banach space either contains $\ell ^1$
or it has an infinite dimensional closed subspace which is a quotient
of a H.I. Banach space.Further on, $L^p(\lambda )$, $1<p<\infty $, is
a quotient of a H.I Banach space.
