CONTENU DES COURS - CONTENTS


**G. GODEFROY (Paris VI) : L'espace $L^1$ et ses sous-espaces.


Resume : L'espace $L^1$ joue un role central en analyse harmonique et en

theorie des probabilites, et son etude permet d'appliquer des outils de

geometrie des espaces de Banach a ces domaines. Nous nous interesserons

plus particulierement aux applications a l'analyse harmonique et a

quelques problemes de lacunarite dans l'ensemble $\bf Z$ des entiers

relatifs. La representation des operateurs sur  $L^1$ sera etudiee et

utilisee. On abordera egalement la question de savoir quels sous espaces

de $L^1$ ont une structure presque discrete, c'est-a-dire sont

arbitrairement proches de  sous-espaces de $\ell^1$, ce qui nous conduira

a utiliser des


methodes probabilistes. Des problemes ouverts de difficulte variee seront

presentes.


**G. GODEFROY (Paris VI): The space $L^1$ and its subspaces.


Schedule : The space $L^1$ has a central place in harmonic analysis and

in probability theory, and its study allows to use tools from the

geometry of Banach spaces in these fields. More specifically, we will

give some application to harmonic analysis and to some problems about

lacunarity in the set $\bb Z$ of the integers. We will study and use the

representation of operators on $L^1$. We will also study the subspaces of

$L^1$ which have an almost discrete structure, i.e. which are arbitrarily

close to subspaces of $\ell_1$, and this will lead us to use

probabilistic tools. Some open problems, of various difficulty, will be

discussed.




**N. KALTON (Missouri-Columbia) : Banach spaces and analytic

semigroups.


Abstract:  We will give an overview of the theory of sectorial operators

and operators with an $H^{\infty}-$calculus, leading up to recent work of

the author, G. Lancien and L. Weis.  Our aim will be to show how modern

concepts in Banach space theory can be applied successfully in this area

to yield new illuminating results.



**T. KORNER (Cambridge) : Applications of Probability to Harmonic

Analysis, First Steps.


Abstract The course will not assume much knowledge of either harmonic

analysis or probability. The contents are not fixed but may include :


 (1) Sphere packing and Shannon's Theorem


 (2) Fourier transforms and normal approximations


 (3) Rearranged Haar series and the reflection principle


 (4) The zero-one law and natural boundaries


 (5) The decay of familly names and Brownian motion



**F. PARREAU (Paris XIII) : Produits de Riesz en theorie ergodique.


But : A travers des calculs explicites sur une classe de constructions,

on montrera des relations etroites entre certains problemes de theorie

ergodique et des problemes d'analyse harmonique des mesures, et on

essaiera de presenter quelques r\'esultats r\'ecents.


Programme : Systemes dynamiques mesurables, type spectral et notions de

melange. Multiplicite spectrale. Des produits de Riesz comme mesures

spectrales : constructions par decoupage et empilement (systemes de

``rang un"), etude spectrale ;  extensions simples, exemples classiques.

Melange faible, fonctions propres et translations des produits de

Riesz.


Criteres de singularite ou de singularite mutuelle des produits de Riesz.

Probleme du spectre simple de Lebesgue et polynomes trigonometriques

``plats". Quelques autres questions de theorie ergodique liees aux

proprietes du type spectral et de ses puissances de convolution.


Exemples obtenus par construction de systemes de rang un.


**F. PARREAU (Paris XIII): Riesz products in ergodic theory.


Goal : through explicit computations on a class of constructions, we will

show connections between problems in ergodic theory and problems in

harmonic analysis of measures, and we shall try to present some recent

results.


Schedule : measurable dynamical systems, spectral type and different

notions of mixing. Spectral multiplicity. Riesz products as spectral

measures: construction by cutting and stacking ("rank-one" systems).

Spectral analysis. Extensions and classical examples. Conditions of weak

mixing. Eigenfunctions and translates of Riesz products. Criteria of

singularity or mutual singularity of Riesz products. The problem of

simple Lebesgue spectrum and flat trigonometric polynomials. Some other

questions of ergodic theory related to harmonic properties of the

spectral type and its convolution powers. Examples obtained by

construction of rank-one systems.

Subject: Abstract of a paper by Daniel Azagra and Mar Jimenez-Sevilla
Date: Tue, 15 Feb 2000 08:42:04 -0600
From: Dale Alspach <alspach at hardy.math.okstate.edu>

This is an announcement for the paper "Rolle's theorem is either false
or trivial in infinite-dimensional   Banach spaces" by Daniel Azagra
and Mar Jimenez-Sevilla.

Abstract: We prove the following new characterization of $C^p$ (Lipschitz)
smoothness in Banach spaces. An infinite-dimensional Banach space $X$
has a $C^p$ smooth (Lipschitz) bump function if and only if it has
another $C^p$ smooth (Lipschitz) bump function $f$ such that $f'(x)\neq
0$ for every point $x$ in the interior of the support of $f$ (that is,
$f$ does not satisfy Rolle's theorem). Moreover, the support of this
bump can be assumed to be a smooth starlike body. As a by-product of
the proof of this result we also obtain other useful characterizations
of $C^p$ smoothness related to the existence of a certain kind of
deleting diffeomorphisms, as well as to the failure of Brouwer's fixed
point theorem even for smooth self-mappings of starlike bodies in all
infinite-dimensional spaces. Finally, we study the structure of the set
of gradients of bump functions in the Hilbert space $\ell_2$, and as a
consequence of the failure of Rolle's theorem in infinite dimensions we
get the following result. The usual norm of the Hilbert space $\ell_2$
can be uniformly approximated by $C^1$ smooth Lipschiz functions $\psi$
so that the cones generated by the sets of derivatives $\psi'(\ell_{2})$
have empty interior.  This implies that there are $C^1$ smooth Lipschitz
bumps in $\ell_{2}$ so that the cones generated by their sets of gradients
have empty interior.

From: Dale Alspach <alspach at hardy.math.okstate.edu>

This is an announcement for the paper "BMO, $H^1$, and Calderon-Zygmund
operators for non doubling measures" by Xavier Tolsa.


Abstract: Given a Radon measure $\mu$ on $R^d$, which may be non doubling,
we introduce a space of type BMO with respect to this measure. It
is shown that many properties that hold when $\mu$ is doubling remain
valid for the space BMO introduced in this paper, without assuming $\mu$
doubling. For instance, Calderon-Zygmund operators which are bounded
in $L^2$ are bounded from $L^\infty$ into the new BMO space. Moreover,
a John-Nirenberg inequality is satisfied, and the predual of BMO is an
atomic space $H^1$. Using a sharp maximal function it is proved that
operators bounded from $L^\infty$ into BMO and from $H^1$ into $L^1$ are
also bounded on $L^p$, $1<p<\infty$. This result gives a new proof of the
T(1) theorem for the Cauchy transform with non doubling measures. Finally,
a result about commutators is obtained.

Subject: Abstract of a paper by Edward Odell and Thomas Schlumprecht
Status: R

This is an announcement for the paper "Trees and branches in Banach
spaces" by Edward Odell and Thomas Schlumprecht.


Abstract: An infinite dimensional notion of asymptotic structure is
considered. This notion is developed in terms of trees and branches
on Banach spaces. Every countably infinite countably branching tree
$\mathcal T$ of a certain type on a space $X$ is presumed to have a
branch with some property. It is shown that then $X$ can be embedded
into a space with an FDD $(E_i)$ so that all normalized sequences in $X$
which are almost a skipped blocking of $(E_i)$ have that property. As
an application of our work we prove that if $X$ is a separable reflexive
Banach space and for some $1<p<\infty$ and $C<\infty$ every weakly null
tree $\mathcal T$ on the sphere of $X$ has a branch $C$-equivalent to
the unit vector basis of $\ell_p$, then for all $\varepsilon>0$, there
exists a finite codimensional subspace of $X$ which $C^2+\varepsilon$
embeds into the $\ell_p$ sum of finite dimensional spaces.

This is an announcement for the paper "Complemented subspaces of locally
convex direct sums of Banach spaces" by Alex Chigogidze.


Abstract: We show that a complemented subspace of a locally convex
direct sum of an uncountable collection of Banach spaces is a locally
convex direct sum of complemented subspaces of countable subsums. As
a corollary we prove that a complemented subspace of a locally convex
direct sum of arbitrary collection of $\ell_{1}(\Gamma )$-spaces is
isomorphic to a locally convex direct sum of $\ell_{1}(\Gamma )$-spaces.

This is an announcement for the paper "Polynomials on Schreier's space"
by Manuel Gonz\'alez and Joaqu\'{\i}n M. Guti\'errez.


Abstract: We introduce a weakened version of the Dunford-Pettis property,
and give examples of Banach spaces with this property. In particular, we
show that every closed subspace of Schreier's space $S$ enjoys it. As an
application, we characterize the weak polynomial convergence of sequences,
show that every closed subspace of $S$ has the polynomial Dunford-Pettis
property of Bistr\"om et al.\ and give other polynomial properties of $S$.

This is an announcement for the paper "The polynomial property (V)"
by Manuel Gonzalez and Joaquin M. Gutierrez.


Abstract: Given Banach spaces $E$ and $F$, we denote by ${\mathcal
P}(^k!E,F)$ the space of all $k$-homogeneous (continuous) polynomials
from $E$ into $F$, and by ${\mathcal P}_{wb}(^k!E,F)$ the subspace of
polynomials which are weak-to-norm continuous on bounded sets. It is
shown that if $E$ has an unconditional finite dimensional expansion of
the identity, the following assertions are equivalent: (a) ${\mathcal
P}(^k!E,F)={\mathcal P}_{wb}(^k!E,F)$; (b) ${\mathcal P}_{wb}(^k!E,F)$
contains no copy of $c_0$; (c) ${\mathcal P}(^k!E,F)$ contains no copy
of $\ell_\infty$; (d) ${\mathcal P}_{wb}(^k!E,F)$ is complemented in
${\mathcal P}(^k!E,F)$. This result was obtained by Kalton for linear
operators. As an application, we show that if $E$ has Pe\l czy\'nski's
property (V) and satisfies ${\mathcal P}(^k!E) ={\mathcal P}_{wb}(^k!E)$
then, for all $F$, every unconditionally converging $P\in{\mathcal
P}(^k!E,F)$ is weakly compact. If $E$ has an unconditional finite
dimensional expansion of the identity, then the converse is also true.

Abstract: Nonreflexive Banach spaces that are complemented in their
bidual by an L-projection - like preduals of von Neumann algebras or
the Hardy space $H^1$ - contain, roughly speaking, many copies of $l^1$
which are very close to isometric copies. Such $l^1$-copies are known
to fail the fixed point property.  Similar dual results hold for $c_0$.

Abstract: Let L_1 be the predual of a von Neumann algebra with a
finite faithful normal trace. We show that a bounded sequence in L_1
converges to 0 in measure if and only if each of its subsequences
admits another subsequence which converges to 0 in norm or spans $l^1$
"almost isometrically". Furthermore we give a quantitative version of
an essentially known result concerning the perturbation of a sequence
spanning $l^1$ isomorphically in the dual of a C$^*$-algebra.

This is an announcement for the paper "L-embedded Banach spaces and

Abstract: An L-embedded Banach spaace is a Banach space which is
complemented in its bidual such that the norm is additive between the
two complementary parts. On such spaces we define a topology, called
an abstract measure topology, which by known results coincides with the
usual measure topology on preduals of finite von Neumann algebras (like
$L_1([0,1])$). Though not numerous, the known properties of this topology
suffice to generalize several results on subspaces of $L_1([0,1])$
to subspaces of arbitrary L-embedded spaces.

This is an announcement for the paper "Spectral radii of bounded operators
on topological vector spaces" by Vladimir G. Troitsky.


Abstract: In this paper we develop a version of spectral theory for
bounded linear operators on topological vector spaces. We show that
the Gelfand formula for spectral radius and Neumann series can still
be naturally interpreted for operators on topological vector spaces. Of
course, the resulting theory has many similarities to the conventional
spectral theory of bounded operators on Banach spaces, though there are
several important differences. The main difference is that an operator
on a topological vector space has several spectra and several spectral
radii, which fit a well-organized pattern.

Subject: Abstract of a paper by Vladimir Pestov
Status: R

This is an announcement for the paper "Ramsey--Milman phenomenon, Urysohn
metric spaces, and extremely amenable   groups" by Vladimir Pestov.


Abstract: In this paper we further study links between concentration of
measure in topological transformation groups, existence of fixed points,
and Ramsey-type theorems for metric spaces. We prove that whenever the
group $\Iso(\U)$ of isometries of Urysohn's universal complete separable
metric space $\mathbb U$, equipped with the compact-open topology,
acts upon an arbitrary compact space, it has a fixed point. The same is
true if $\U$ is replaced with any generalized Urysohn metric space $U$
that is sufficiently homogeneous. Modulo a recent theorem by Uspenskij
that every topological group embeds into a topological group of the form
$\Iso(U)$, our result implies that every topological group embeds into
an extremely amenable group (one admitting an invariant multiplicative
mean on bounded right uniformly continuous functions). By way of the
proof, we show that every topological group is approximated by finite
groups in a certain weak sense. Our technique also results in a new
proof of the extreme amenability (fixed point on compacta property) for
infinite orthogonal groups. Going in the opposite direction, we deduce
some Ramsey-type theorems for metric subspaces of Hilbert spaces and for
spherical metric spaces from existing results on extreme amenability of
infinite unitary groups and groups of isometries of Hilbert spaces.

This is an announcement for the paper "The Dunford-Pettis property on
tensor products" by Manuel Gonzalez and Joaquin M. Gutierrez.


Abstract: We show that, in some cases, the projective and the
injective tensor products of two Banach spaces do not have
the Dunford-Pettis property (DPP). As a consequence, we obtain
that $(c_0\widehat{\otimes}_\pi c_0)^{**}$ fails the DPP. Since
$(c_0\widehat{\otimes}_\pi c_0)^{*}$ does enjoy it, this provides a new
space with the DPP whose dual fails to have it. We also prove that, if $E$
and $F$ are ${\mathscr L}_1$-spaces, then $E\widehat{\otimes}_\epsilon F$
has the DPP if and only if both $E$ and $F$ have the Schur property. Other
results and examples are given.

This is an announcement for the paper "Sequences in non-commutative
$L^p$-spaces" by Narcisse Randrianantoanina.


Abstract: Let $\cal M$ be a semi-finite von Neumann algebra equipped
with a distinguished faithful, normal, semi-finite trace $\tau$. We
introduce the notion of equi-integrability in non-commutative spaces
and show that if a rearrangement invariant quasi-Banach function space
$E$ on the positive semi-axis is $\alpha$-convex with constant $1$ and
satisfies a non-trivial lower $q$-estimate with constant $1$, then the
corresponding non-commutative space of measurable operators $E({\cal M},
\tau)$ has the following property: every bounded sequence in $E({\cal M},
\tau)$ has a subsequence that splits into a $E$-equi-integrable sequence
and a sequence with pairwise disjoint projection supports. This result
extends the well known Kadec-Pe\l czy\'nski subsequence decomposition
for Banach lattices to non-commutative spaces. As applications, we prove
that for $1\leq p <\infty$, every subspace of $L^p(\cal M, \tau)$ either
contains almost isometric copies of $\ell^p$ or is strongly embedded in
$L^p(\cal M, \tau)$.

This is an announcement for the paper "Embeddings of $\ell_p$ into
non-commutative spaces" by Narcisse Randrianantoanina.


Abstract: Let $\M$ be a semi-finite von Neumann algebra equipped with
a faithful normal trace $\tau$. We study the subspace structures of
non-commutative Lorentz spaces $L_{p,q}(\M, \tau)$, extending results of
Carothers and Dilworth to the non-commutative settings. In particular,
we show that, under natural conditions on indices, $\ell_p$ can not be
embedded into $L_{p,q}(\M, \tau)$. As applications, we prove that for
$0<p<\infty$ with $p \neq 2$ then $\ell_p$ cannot be strongly embedded
into $L_p(\M,\tau)$. Thus providing a non-commutative extension of a
result of Kalton for $0<p<1$ and a result of Rosenthal for $1\leq p <2$
on $L_p[0,1]$.

This is an announcement for the paper "Functions of Baire class one"
by Denny H. Leung and Wee-Kee Tang.


Abstract: Let $K$ be a compact metric space. A real-valued function on
$K$ is said to be of Baire class one (Baire-$1$) if it is the pointwise
limit of a sequence of continuous functions. In this paper, we study
two well known ordinal indices of Baire-$1$ functions, the oscillation
index $\beta$ and the convergence index $\gamma$. It is shown that
these two indices are fully compatible in the following sense : a
Baire-$1$ function $f$ satisfies $\beta(f) \leq \omega^{\xi_1} \cdot
\omega^{\xi_2}$ for some countable ordinals $\xi_1$ and $\xi_2$ if and
only if there exists a sequence of Baire-$1$ functions $(f_n)$ converging
to $f$ pointwise such that $\sup_n\beta(f_n) \leq \omega^{\xi_1}$
and $\gamma((f_n)) \leq \omega^{\xi_2}$. We also obtain an extension
result for Baire-$1$ functions analogous to the Tietze Extension
Theorem. Finally, it is shown that if $\beta(f) \leq \omega^{\xi_1}$
and $\beta(g) \leq \omega^{\xi_2},$ then $\beta(fg) \leq \omega^{\xi},$
where $\xi=\max\{\xi_1+\xi_2,\,\xi_2+\xi_1}\}.$ These results do not
assume the boundedness of the functions involved.

Abstract: A condition for the presence of a "gap" between symmetric spaces
sufficient for the inclusion of one of these spaces into the other to be
disjointly strictly singular is found. This condition is stated in terms
of fundamental functions of spaces and is exact in a certain sense. In
parallel, necessary and sufficient conditions for an inclusion of Lorentz
spaces to be disjointly strictly singular are obtained.

This is an announcement for the paper "Decomposition of analytic
measures on groups and measure spaces" by Nakhle Asmar and Stephen
Montgomery-Smith.


Abstract: This paper provides a new approach to proving generalizations
of the F.&M.  Riesz Theorem, for example, the result of Helson and
Lowdenslager, the result of Forelli (and de Leeuw and Glicksberg),
and more recent results of Yamagushi.  We study actions of a locally
compact abelian group with ordered dual onto a space of measures, and
consider those measures that are analytic, that is, the spectrum of the
action on the measure is contained within the positive elements of the
dual of the group. The classical results tell us that the singular and
absolutely continuous parts of the measure (with respect to a suitable
measure) are also analytic. The approach taken in this paper is to
adopt the transference principle developed by the authors and Saeki in
another paper, and apply it to martingale inequalities of Burkholder
and Garling. In this way, we obtain a decomposition of the measures,
and obtain the above mentioned results as corollaries.

Status: R

This is an announcement for the paper "Banach embedding properties
of non-commutative L^p-spaces" by U. Haagerup, H.P. Rosenthal and
F.A. Sukochev.


Abstract: Let N and M be von Neumann algebras. It is proved that
L^p(N) does not Banach embed in L^p(M) for N infinite, M finite, 1 <
or = p < 2. The following considerably stronger result is obtained
(which implies this, since the Schatten p-class C_p embeds in L^p(N)
for N infinite). Theorem: Let 1 < or = p < 2 and let X be a Banach
space with a spanning set (x_{ij}) so that for some C < or = 1:
(i) any row or column is C-equivalent to the usual ell^2-basis; (ii)
(x_{i_k,j_k}) is C-equivalent to the usual ell^p-basis, for any i_1 <
i_2 < ...  and j_1 < j_2 < ... . Then X is not isomorphic to a subspace
of L^p(M), for M finite. Complements on the Banach space structure
of non-commutative L^p-spaces are obtained, such as the p-Banach-Saks
property and characterizations of subspaces of L^p(M) containing ell^p
isomorphically. The spaces L^p(N) are classified up to Banach isomorphism,
for N infinite-dimensional, hyperfinite and semifinite, 1 < or = p< infty,
p not= 2. It is proved that there are exactly thirteen isomorphism types;
the corresponding embedding properties are determined for p < 2 via
an eight level Hasse diagram. It is also proved for all 1 < or = p <
infty that L^p(N) is completely isomorphic to L^p(M) if N and M are the
algebras associated to free groups, or if N and M are injective factors
of type III_lambda and III_{lambda'} for 0 < lambda, lambda' < or = 1.

Subject: Abstract of a paper by C. A. Akemann, G. C. Shell, and N. Weaver
Status: R

This is an announcement for the paper "Locally nonconical convexity"
by C. A. Akemann, G. C. Shell, and N. Weaver.


Abstract: There is a hierarchy of structure conditions for convex sets. In
this paper we study a recently defined [3, 8, 9] condition called locally
nonconical convexity (abbreviated LNC). Is is easy to show that every
strictly convex set is LNC, as are half-spaces and finite intersections of
sets of either of these types, but many more sets are LNC. For instance,
every zonoid (the range of a nonatomic vector-valued measure) is LNC
(Corollary 34). However, there are no infinite-dimensional compact LNC
sets (Theorem 23).
  The LNC concept originated in a search for continuous sections, and the
present paper shows how it leads naturally (and constructively) to
continuous sections in a variety of situations. Let Q be a compact,
convex set in R<sup>n</sup>, and let T be a linear map from R<sup>n</sup>
into R<sup>m</sup>.  We show (Theorem 1) that Q is LNC if and only if
the restriction of any such T to Q is an open map of Q onto T(Q). This
implies that if Q is LNC, then any such T has continuous sections
(i.e. there are continuous right inverses of T) that map from T(Q) to Q,
and in fact it is possible to define continuous sections constructively
in various natural ways (Theorem 3, Corollary 4, and Theorem 5). If Q is
strictly convex and T is not 1-1, we can construct continuous sections
which take values in the boundary of Q (Theorem 6).
  When we give up compactness it is natural to consider a closed,
  convex, LNC
subset Q of a Hilbert space X which may be infinite-dimensional. In
this case we must assume that T is left Fredholm, i.e. a bounded linear
map with closed range and finite-dimensional kernel. We can then prove
results analogous to those mentioned in the last paragraph (Theorems
16-20). We also prove that T(Q) is LNC (Theorem 25).

This is an announcement for the paper "A general approach to narrow
operators and rich subspaces of Banach   spaces" by Vladimir Kadets,
Roman Shvidkoy, and Dirk Werner.


Abstract: Let $X$ be a Banach space. We introduce a formal approach which
seems to be useful in the study of those properties of operators on $X$
which depend only on the norms of elements. This approach is applied to
the Daugavet equation for norms of operators; in particular we develop a
general theory of narrow operators and rich subspaces of $X$ previously
studied in the context of the classical spaces $C(K)$ and $L_1(\mu)$.

This is an announcement for the paper "Summing inclusion maps between
symmetric sequence spaces" by Andreas Defant, Mieczyslaw Mastylo and
Carsten Michels.


Abstract: We prove a substantial extension of a well-known result due to
Bennett and Carl: The inclusion of a 2-concave symmetric Banach sequence
space E into l_2 is (E,1)-summing, i.e. for every unconditionally summable
sequence (x_n) in E the scalar sequence (||x_n||_2) is contained in
E. Various applications are given, e.g. to the theory of eigenvalue
distribution of compact operators and approximation theory.

Abstract: Following Davie's example of a Banach space failing the
approximation property [D], we show how to construct a Banach space
E which is asymptotically Hilbertian and fails the approximation
property. Moreover, the space E is shown to be a subspace of a space
with an unconditional basis which is ``almost'' a weak Hilbert space
and which can be written as the direct sum of two subspaces all of whose
subspaces have the approximation property.

http://www.math.tamu.edu/research/workshops/linanalysis/

The Home Page also contains other information about the Workshop, including
a list of participants and a schedule of seminars.


Housing: Contact Cheryl Rogers, (cherylr at math.tamu.edu;  979/845-2915,
office; 979/ 845-6028, fax) for help with housing. Please tell Cheryl the
type of accommodation you desire (smoking or nonsmoking), which night(s) 
you need the room, and give her a roommate preference, if applicable.

We expect to be able to cover housing, possibly in a double room, for most
participants, from support the National Science Foundation has provided for
the Workshop. Preference will be given to participants who do not have other
sources of support, such as sponsored research grants. When you ask Cheryl
to book your room, please tell her if you are requesting support. Rooms in
CS are tight the weekend of SUMIRFAS as this is graduation weekend, 
so please act ASAP.


Dinner:  There will be a dinner at 6:30 p.m. on Saturday, August 12,  at
Imperial Chinese Restaurant, 2232 S. Texas Ave. in College  Station. The
cost for the subsidized dinner is $15 per person for faculty and $10 per
person for students. Please tell Cheryl Rogers if  you (and spouse or
companion, if applicable) will attend. Checks should be made out to Math.
Dept., TAMU.

            **  DINNER RESERVATIONS SHOULD  BE MADE BY AUGUST 9
                     and PAYMENT MADE BY AUGUST 12. **

This is an announcement for the paper "Embeddings of rearrangement
invariant spaces that are not strictly   singular" by
S.J. Montgomery-Smith and E.M. Semenov.


Abstract: We give partial answers to the following conjecture: the
natural embedding of a rearrangement invariant space E into L_1([0,1])
is strictly singular if and only if G does not embed into E continuously,
where G is the closure of the simple functions in the Orlicz space L_Phi
with Phi(x) = exp(x^2)-1.

            Spring School on Function Spaces and Interpolation

                             First Announcement


     Dear Colleague,

   Following a longstanding tradition, the Faculty of Mathematics and
   Physics of Charles University in Prague will organize a

       Spring School on Function Spaces and Interpolation.


The School will be held at Paseky nad Jizerou, in a chalet
in the Krkonose Mountains, May 27 - June 2, 2001. The program will
consist of the following series of lectures:


Andrea Cianchi (University of Florence, Italy):
Rearrangement estimates and applications to Sobolev and related
inequalities,

Michael Cwikel (Technion, Haifa, Israel):
Calderon couples and K-divisibility,

Mario Milman (Florida Atlantic University, Boca Raton, U.S.A.):
Extrapolation: New results and Applications.


More details and the registration form can be found at the URL address

http://www.karlin.mff.cuni.cz/katedry/kma/ss/jun01/ss.htm

       The conference fee will be approximately USD 340. A discount will
       be offered provided that a letter guaranteeing participation
       reaches the organizers before February 15, 2001. The conference
       fee includes all local expenses (room and board) and
       transportation between Prague and Paseky. The fee for accompanying
       persons is the same.

       The organizers may provide financial support to a limited number
       of students. Applications must be sent before February 15, 2001.

       The village of Paseky lies in the slopes of the Krkonose Mountains
       in North Bohemia. Accommodation consists of rooms for two or three
       people. There are excellent facilities and conditions for sporting
       activities: hiking trips, soccer, mini-golf and sauna.

       A special bus from Prague to Paseky will leave at 4 p.m. on May
       27, 2001. The bus from Paseky will arrive in Prague on June 2,
       2001 at 11.30 a.m.

       Kindly inform your colleagues and students interested in this field.
       We look forward to meeting you in the Czech Republic.

This is an announcement for the paper "Inequalities for the Gamma function
and estimates for the volume of sections of $B_p^n$" by Jesus Bastero,
Fernando Galve, Ana Pena, and Miguel Romance.


Abstract: We consider $k$-dimensional central sections of the unit
ball of $\ell_p^n$ (denoted $B_p^n$) and we prove that their volume are
bounded by the volume of $B_p^n$ whenever $1<p<2$ and $1\le k\le (n-1)/2$
or $k=n-1$. We also consider $0<p<1$ and other cases. We obtain sharp
inequalities involving Gamma Function in order to get these results.

This is an announcement for the paper "Integral mappings and the principle
of local reflexivity for   noncommutative L^1-spaces" by Edward G. Effros,
Marius Junge and Zhong-Jin Ruan.


Abstract: The operator space analogue of the {\em strong form} of the
principle of local reflexivity is shown to hold for any von Neumann
algebra predual, and thus for any $C^{*}$-algebraic dual. This is
in striking contrast to the situation for $C^{*}$-algebras, since,
for example, $K(H)$ does not have that property. The proof uses the
Kaplansky density theorem together with a careful analysis of two notions
of integrality for mappings of operator spaces.

This is an announcement for the paper "Selection of subsystems of
random variables equivalent in distribution to the Rademacher system"
by S.V.Astashkin.


Abstract: We present necessary and sufficient conditions on systems of
random variables for them to possess a lacunary subsystem equivalent in
distribution to the Rademacher system on the segment [0,1]. In particular,
every uniformly bounded orthonormal system has this property. Furthermore,
an arbitrary finite uniformly bounded orthonormal set of N functions
contains a subset of "logarithmic" density equivalent in distribution
to the corresponding set of Rademacher functions, with a constant
independent of N. A connection between the tail distribution and the
L_p-norms of polynomials with respect to systems of random variables
exploited. We use also these results to study K-closed representability
of some Banach couples.

by E. Munoz-Garcia.


Abstract: A metric vector space is asymptotically metrically normable
(AMN) if there exists a norm asymptotically isometric to the distance. We
prove that AMN vector spaces are rigid in the class of metric vector
spaces under asymptotically isometric perturbations. This result follows
from a general metric normability criterium.
 If the distance is translation invariant and satisfies an approximate
multiplicative condition then there exists a lipschitz equivalent norm.
Furthermore, we give necessary and sufficient conditions for the distance
to be asymptotically isometric to the norm.

Abstract: We define the ($w^\ast$-) boundedness property and the

that these properties are pairwise equivalent in complete normed spaces
by characterizing them in terms of a category-like property called
($w^\ast$-) thickness. We give examples of interesting sets having or not
having these properties. In particular, we prove that the tensor product
of two $w^\ast$-thick sets in $\Xastast$ and $\Yast$ is a $w^\ast$-thick
subset in $L(X,Y)^\ast$ and obtain as a concequense that the set $w^\ast
-exp\:B_{K(l_2)^\ast}$ is $w^\ast$-thick.

This is an announcement for the paper "Remarks on the similarity degree
of an operator algebra" by Gilles Pisier.


Abstract: The ``similarity" degree of a unital operator algebra $A$ was
defined and studied in two recent papers of ours, where in particular we
showed that it coincides with the ``length" of an operator algebra. This
paper brings several complements: we give direct proofs (with slight
improvements) of several known facts on the length which were only known
via the degree, and we show that the length of a type $II_1$ factor with
property $\Gamma$ is at most 5, improving on a previous bound ($\le 44$)
due to E. Christensen.

Subject: Abstract of a paper by Gilles Pisier
Status: R

This is an announcement for the paper "Multipliers of the Hardy space
$H^1$ and power bounded operators" by Gilles Pisier.


Abstract: We study the space of functions $\varphi\colon \ \NN\to \CC$
such that there is a Hilbert space $H$, a power bounded operator $T$
in $B(H)$ and vectors $\xi,\eta$ in $H$ such that $$\varphi(n) = \langle
T^n\xi,\eta\rangle.$$ This implies that the matrix $(\varphi(i+j))_{i,j\ge
0}$ is a Schur multiplier of $B(\ell_2)$ or equivalently is in the
space $(\ell_1 \buildrel {\vee}\over {\otimes} \ell_1)^*$. We show that
the converse does not hold, which answers a question raised by Peller
[Pe]. Our approach makes use of a new class of Fourier multipliers of
$H^1$ which we call ``shift-bounded''. We show that there is a $\varphi$
which is a ``completely bounded'' multiplier of $H^1$, or equivalently
for which $(\varphi(i+j))_{i,j\ge 0}$ is a bounded Schur multiplier of
$B(\ell_2)$, but which is not ``shift-bounded'' on $H^1$. We also give
a characterization of ``completely shift-bounded'' multipliers on $H^1$.

Abstract: Let X be an L_1-predual space and let K be a countable linearly
independent subset of the extreme points of its closed dual ball. It
is shown that if the norm-closed linear span Y of K is w^*-closed in
X^*, then Y is the range of a w^*-continuous contractive projection in
X^*. This result is applied in order to provide new and simpler proofs of
the results of Lazar, Lindenstrauss and Zippin on the embedding of C(K)
spaces into X.

Abstract: Following Davie's example of a Banach space failing the
approximation property [D], we show how to construct a Banach space
E which is asymptotically Hilbertian and fails the approximation
property. Moreover, the space E is shown to be a subspace of a space
with an unconditional basis which is ``almost'' a weak Hilbert space
and which can be written as the direct sum of two subspaces all of whose
subspaces have the approximation property.

This is an announcement for the paper "The Szlenk index and local
l_1-indices" by Dale Alspach, Robert Judd, and Edward Odell.


Abstract: We introduce two new local l_1-indices of the same type as the
Bourgain l_1 index; the l_1^+-index and the l_1^+-weakly null index. We
show that the l_1^+-weakly null index of a Banach space X is the same as
the Szlenk index of X, provided X does not contain l_1. The l_1^+-weakly
null index has the same form as the Bourgain l_1 index: if it is countable
it must take values omega^alpha for some alpha<omega_1. The different
l_1-indices are closely related and so knowing the Szlenk index of a
Banach space helps us calculate its local l_1-index, via the l_1^+-weakly
null index. We show that I(C(omega^{omega^alpha}))=omega^{1+alpha+1}.

This is an announcement for the paper "The Marcinkiewicz multiplier
condition for bilinear operators" by Loukas Grafakos and Nigel Kalton.


Abstract: This article is concerned with the question of whether
Marcinkiewicz multipliers on $\mathbb R^{2n}$ give rise to bilinear
multipliers on $\mathbb R^n\times \mathbb R^n$. We show that this is not
always the case. Moreover we find necessary and sufficient conditions for
such bilinear multipliers to be bounded. These conditions in particular
imply that a slight logarithmic modification of the Marcinkiewicz
condition gives multipliers for which the corresponding bilinear operators
are bounded on products of Lebesgue and Hardy spaces.

This is an announcement for the paper "The $H^{\infty}-$calculus and
sums of closed operators" by N.J. Kalton and L. Weis.


Abstract: We develop a very general operator-valued functional calculus
  for operators with an $H^{\infty}-$calculus. We then apply this to the
  joint functional calculus of two commuting sectorial operators when one
  has an $H^{\infty}$calculus. Using this we prove theorem of Dore-Venni
  type on sums of commuting sectorial operators and apply our results
  to the problem of $L_p-$maximal regularity.  Our main assumption is
  the R-boundedness of certain sets of operators, and therefore methods
  from the geometry of Banach spaces are essential here.  In the final
  section we exploit the special Banach space structure of $L_1-$spaces

IV Conference in Banach Spaces

Dear colleague, the Department of Mathematics of the University of
Extremadura organizes the IV Conference on Banach Spaces during the week
18-22 December 2000. The meeting shall take place in the Centro de Estudios
of the University in Jarandilla de la Vera, Cáceres, Spain. 
   The Conference is organized in three sections or seminars, each focused
(more or less freely) on a topic. This time they are:

   1. Tensor products of Banach spaces. So far it has been confirmed the
participation of F. Blasco, R. García, P. Galindo, J. Jaramillo and J.L.
Llavona.
   2. Topological methods in function spaces. So far it has been confirmed
the participation of V. Fonf, I. Garrido, M. Jiménez, A. Plichko and B.
Radrianantoanina.
   3. Algebraic methods in Banach spaces (and related structures). So far
it has been confirmed the participation of F. Cabello, JMF Castillo, A.Y.
Helemskii, N. Kalton, P. Papini and D. Yost.

   As in the previous meetings, we hope to provide a friendly and
stimulating working atmosphere. The ambience during the talks is relaxed
and open to participation; actually, some shorter conferences could be
included in the seminars. In addition to this, there have been organized
some sections for communications. Those interested in delivering a shorter
talk or communication are invited to submit an abstract with the contents;
if it is intended to
be included in a seminar, please indicate in which one you think it fits
better.
   Unfortunately there is only a limited number of rooms in the Centro de
Estudios (4.000 pts/day, including meals). So, those interested in
participating are invited to contact with the organizators (see below) as
soon as possible so that we can make the reservation. There shall be a
conference fee of 15.000 pts (100 $) for doctors and 4.000 pts (25 $) for
non-doctors.
The proceedings of the Conference shall be published in Extracta
Mathematicae.

Abstract: For realcompact spaces X and Y we give a complete description of
the linear biseparating maps between spaces of vector-valued continuous
functions on X and Y, where special attention is paid to spaces of
vector-valued bounded continuous functions. These results are applied to
describe the linear isometries between spaces of vector-valued bounded
continuous and uniformly continuous functions.

       The conference fee will be USD 340. A reduced rate of USD 290
       will be offered provided that a letter guaranteeing participation
       reaches the organizers before January 15, 2001. The conference
       fee includes all local expenses (room and board) and transportation
       between Prague and Paseky. The fee for accompanying persons is
       the same.


       Payment of the fee should be made in cash at the registration
       desk in Paseky, or it may be remitted by a bank transfer to

          Komercni banka, Praha 1, Vaclavske nam. 42
          account No. 38330-021/0100, v.s. 30300-0029

       (a copy of the transfer slip should be presented at the
       registration desk at Paseky). Unfortunately, neither cheques nor
       credit cards can be used and will not be accepted.


       The organizers may provide financial support to a limited number
       of students. Applications must be sent before January 15, 2001.

       The village of Paseky lies in the slopes of the Krkonose
       Mountains in North Bohemia. Accommodation consists of rooms
       for two or three people.

       A single room can be arranged on demand if the capacity of the
       chalet allows. In such case additional USD 100 will be charged.

       The vicinity of the chalet is suitable for wonderful hiking
       trips. Moreover, there are excellent facilities for various
       sporting activities: soccer, mini-golf, fitness center, snooker,
       darts and sauna.

       A special bus from Prague to Paseky will leave at 4 p.m. on April
       15, 2001. The bus from Paseky will arrive in Prague on April 21,
       2001 at 11.30 a.m.

       The last announcement containing more details will
       be distributed in due time.

       Kindly inform your colleagues and students interested in this
       field.

       We look forward to meeting you in the Czech Republic.

Subject: Abstract of a paper by R. Vershynin
Status: R

This is an announcement for the paper "Coordinate restrictions of linear
operators in $l_2^n$" by R. Vershynin.


Abstract: This paper addresses the problem of improving properties
of a linear operator $u$ in $l_2^n$ by restricting it onto coordinate
subspaces. We discuss how to reduce the norm of $u$ by a random coordinate
restriction, how to approximate $u$ by a random operator with small
"coordinate" rank, how to find coordinate subspaces where $u$ is an
isomorphism. The first problem in this list provides a probabilistic
extension of a suppression theorem of Kashin and Tzafriri, the second
one is a new look at a result of Rudelson on the random vectors in the
isotropic position, the last one is the recent generalization of the
Bourgain-Tzafriri's invertibility principle. The main point is that all
the results are independent of $n$, the situation is instead controlled
by the Hilbert-Schmidt norm of $u$. As an application, we provide an
almost optimal solution to the problem of harmonic density in harmonic
analysis, and a solution to the reconstruction problem for communication
networks which deliver data with random losses.

This is an announcement for the paper "Extremal approximately convex
functions and the best constants in a   theorem of Hyers and Ulam"
by S. J. Dilworth, Ralph Howard and James W. Roberts.


Abstract: Let $n\ge1$ and $B\ge2$. A real-valued function $f$ defined
on the $n$-simplex $\Delta_n$ is approximately convex with respect to
$\Delta_{B-1}$ iff
  f(\sum_{i=1}^B t_ix_i ) \le \sum_{i=1}^B t_if(x_i) +1 for all
  $x_1,\dots,x_B \in \Delta_n$ and all $(t_1,\dots,t_B)\in
\Delta_{B-1}$. We determine explicitly the extremal (i.e. pointwise
largest) function of this type which vanishes on the vertices of
$\Delta_n$. We also prove a stability theorem of Hyers-Ulam type which
yields as a special case the best constants in the Hyers-Ulam stability
theorem for $\epsilon$-convex functions.
