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 get banach ssacconetight.tex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 93444 bytes

From alspach Tue Jan 28 13:07:53 1997 To: banach Subject: Abstract of a paper by Stanislaw J. Szarek Content-Length: 1418
This is the abstract of the paper "Metric entropy of homogeneous spaces and Finsler geometry of classical Lie groups" by Stanislaw J. Szarek. The paper is typed in LaTeX2.09. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach szarekentropy.latex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 68058 bytes

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach njlktheory.latex to: majordomo at littlewood.math.okstate.edu. 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.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach koldobskyisocharlp.tex to: majordomo at littlewood.math.okstate.edu. 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.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach MCBapproxLipsConv.tex to: majordomo at littlewood.math.okstate.edu. Abstract:In this paper we give some results about the approximation of a Lipschitz function on a Banach space by means of $\Delta$-convex 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. File Length: 43570 bytes

Abstract:Let $M$ be a von Neumann algebra with a faithful normal finite trace $t$, and $H^\infty$ be a finite, maximal, subdiagonal of $M$. Fundamental theorems on conjugate functions for weak* Dirichlet 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 $L^1(M,t)$. File Length: 50253 bytes

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 $N(\epsilon)$.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach oikhbergpisiermaxten.tex to: majordomo at littlewood.math.okstate.edu. 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.

\magnification=1200 \centerline{\bf A NEW BOOK:} \medskip \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.. \bigskip \settabs 2 \columns \+ \it USA Customers: & \it European Customers: \cr \+ & \cr \+ \rm John Wiley \& Sons, Inc. & John Wiley \& Sons, Ltd. \cr \+ Distribution Center & Distribution Centre \cr \+ 1 Wiley Drive & Souther Cross Trading Estate \cr \+ Somerset, NJ 08875-1272 & 1 Oldlands Way \cr \+ telephone: (908) 469-4400 & Bognor Regis \cr \+ fax: (908) 302-2300 & Sussex PO 22 9SA \cr \+ e-mail: custserv at wiley.com & England \cr \+ & telephone: 44 0243 779777 \cr \+ & fax: 44 0243 820250 \cr\bigskip\bigskip \medskip {\it Price: US dollars: 64.95} \bigskip \rightline{Mari\'a=A0n Fabian} \rightline{Mathematical Institue} \rightline{Czech Academy of Sciences} \rightline{\v Zitn\'a 25, 11 567 Prague 1} \rightline{Czech Republic} \rightline{e-mail: fabian at karlin.mff.cuni.cz} \bye

This is the abstract of the paper "Modified mixed Tsirelson spaces" by S. A. Argyros, I. Deliyanni, D. Kutzarova, and A. Manoussakis. The paper is typed in LaTeX2.09. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach argdelkutzmanmodmxdtsrlsn.latex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 161092 bytes

For example, we show that if $\A$ is infinite, then every such linear preserver can be written as a fixed unitary operator times either a unital *-homomorphism or a unital *-antihomomorphism.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach pisiersimdegopalg.tex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 141532 bytes

Furthermore, we prove that in the case of extensions of C(H) by separable commutative C*-algebras, these groups are algebraically 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.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach cepedboisoregsuprefcnvltn.tex to: majordomo at littlewood.math.okstate.edu. 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.

We then show that a large class of Fenchel-Orlicz spaces on ${\rm {\bf R}}^n$ can be renormed to have property (M).

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach neuwirthumapFourier.latex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 126738 bytes

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 anc_grey.ps grey-scale anc_bw.ps black-white anc_col.doc Word color anc_grey.doc grey-scale anc_bw.doc black-white anc_la.tex LaTeX (no logo) anc.asc ASCII (no logo) logo_col.ps Logo encapsulated Postscript color logo_grey.ps grey-scale logo_bw.ps black-white 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!

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. ----------------------------------------------------------------- Organization ----------------------------------------------------------------- Up-to-date information about all aspects of ICM'98 is available on the following website: http://elib.zib.de/ICM98 This includes information about registration, abstract submission, etc. Correspondence should be directed to icm98 at zib.de It will be forwarded to an appropriate member of the Organizing Committee.

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'.

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 AMSTeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach rosenthalgroth.tex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 32083 bytes

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach kaltoncommut.tex to: majordomo at littlewood.math.okstate.edu. 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.

This is the abstract of the paper "Distances between Banach spaces" by N.J. Kalton and M.I. Ostrovskii. The paper is typed in AMSTeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach kaltonostrovdist.tex to: majordomo at littlewood.math.okstate.edu. 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. File Length: 79013 bytes

This is the abstract of the paper "Nonlinear equations and weighted norm inequalities" by N.J. Kalton and I.E. Verbitsky. The paper is typed in AMSTeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach kaltonverbitsknonlinear.tex to: majordomo at littlewood.math.okstate.edu. 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.

Abstract:For countably generated ideals, $\Jc$, of $B(\Hil)$, geometric stability is necessary for the canonical spectral characterization of sums of $(\Jc,B(\Hil))$--commutators to hold. 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. File Length: 48103 bytes

Abstract:We show that Rudin-Plotkin isometry extension theorem in $L_p$ implies that when $X$ and $Y$ are isometric subspaces of $L_p$ and $p$ is not an even integer, $1 \leq p < \infty$, then $X$ is 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. File Length: 42751 bytes

This is the abstract of the paper "Noncommutative interpolation and Poisson transforms" by Alvaro Arias and Gelu Popescu. The paper is typed in AMSTeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach ariaspopescuinterpolation.tex to: majordomo at littlewood.math.okstate.edu. Abstract:General results of interpolation (eg. Nevanlinna-Pick) by elements in the noncommutative analytic Toeplitz algebra $F^\infty$ (resp. noncommutative disc algebra $A_n$) with consequences to the interpolation by bounded operator-valued analytic functions in the unit ball of ${\bf C}^n$ are obtained. 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 algebra $F^\infty/J$ are considered. File Length: 85698 bytes

This is the abstract of the paper "Banach spaces with the Daugavet property" by Vladimir Kadets, Roman Shvidkoy, Gleb Sirotkin and Dirk Werner. The paper is typed in LaTeX2.09. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach kadetsshvidsirotwernerdaug.latex to: majordomo at littlewood.math.okstate.edu. 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.

Announcing: The Fall 1997 Show-Me Meeting December 5 1997 University of Missouri-Columbia Physics Building 114 3:00 - 5:30 p.m. Main Speakers: Michael Lacey: On the role of Carleson's Theorem in Analysis Alan McIntosh: Spectral Theory and Harmonic Analysis There will be a dinner afterwards at 6:00p.m. for a reasonable charge. Contact stephen at math.missouri.edu for more information and dinner reservations (please inform me if you have any special dietary requirements.) 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.

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. File Length: 8903 bytes

This is the abstract of the paper "Nonlinear quotients" by S. Bates, W. B. Johnson, J. Lindenstrauss, D. Preiss, and G. Schechtman. 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 get banach batjohlinpreschquotients.tex to: majordomo at littlewood.math.okstate.edu. 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.

This is the abstract of the paper "Interpolating hereditarily indecomposable Banach spaces" by S.A. Argyros and V. Felouzis. The paper is typed in LaTeX2e. There are some problems with the laTeX so the postscript file is also available. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach argyrosfelouzisintrphi.latex or get banach argyrosfelouzisintrphi.ps to: majordomo at littlewood.math.okstate.edu. 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 $, is a quotient of a H.I Banach space. File Length: 235187 bytes, 614948 bytes
From alspach Mon Jan 19 15:22:25 1998 To: banach Subject: Abstract of a paper by M. Meyer and E. Werner Content-Length: 648
This is the abstract of the paper "On the p-affine surface area" by M. Meyer and E. Werner. The paper is typed in LaTeX2e. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the command get banach meyerwern2.latex to: majordomo at littlewood.math.okstate.edu. Abstract:We give geometric interpretations of certain affine invariants of convex bodies. The affine invariants are the p-affine surface areas introduced by Lutwak. The geometric interpretations involve generalizations of the Santal${\mbox{\'o}}$-bodies introduced by the authors in a previous paper. File Length: 112130 bytes
