Abstract of a paper by Daniel Carando, Silvia Lassalle, and Pablo Schmidberg

This is an announcement for the paper "The reconstruction formula for Banach frames and duality" by Daniel Carando, Silvia Lassalle, and Pablo Schmidberg. Abstract: We study conditions on a Banach frame that ensures the validity of a reconstruction formula. In particular, we show that any Banach frames for (a subspace of) $L_p$ or $L_{p,q}$ ($1\le p < \infty$) with respect to a solid sequence space always satisfies an unconditional reconstruction formula. The existence of reconstruction formulae allows us to prove some James-type results for atomic decompositions: an unconditional atomic decomposition (or unconditional Schauder frame) for $X$ is shrinking (respectively, boundedly complete) if and only if $X$ does not contain an isomorphic copy of $\ell_1$ (respectively, $c_0$).

This is an announcement for the paper "Operator ideals arising from generating sequences" by Ngai-Ching Wong. Abstract: In this note, we will discuss how to relate an operator ideal on Banach spaces to the sequential structures it defines. Concrete examples of ideals of compact, weakly compact, completely continuous, Banach-Saks and weakly Banach-Saks operators will be demonstrated.

This is an announcement for the paper "On multi-ideals and polynomial ideals of Banach spaces" by Daniel Pellegrino and Joilson Ribeiro. Abstract: The notion of coherent sequences of polynomial ideals and the notion of compatibility of a polynomial ideal with a given operator ideal were recently introduced by D. Carando, V. Dimant and S. Muro. These concepts play an important role in the theory of polynomial ideals, since they offer some properties that polynomial ideals must satisfy in order to keep the spirit of a given operator ideal and also maintain some coherence between the different levels of $n$-homogeneity. However, it seems to exist no reason to omit the multi-ideals from these cycle of ideas. In the present paper we revisit these notions; more precisely, we propose that these concepts are considered for a pair $(\mathcal{P}_{k},\mathcal{M}_{k})_{k=1}^{\infty}$, where $(\mathcal{P}% _{k})_{k=1}^{\infty}$ is a polynomial ideal and $(\mathcal{M}_{k}% )_{k=1}^{\infty}$ is a multi-ideal. The construction of our approach is inspired by the important special case of absolutely summing operators.

This is an announcement for the paper "Some remarks on absolutely summing multilinear operators" by Adriano Thiago L. Bernardino and Daniel Pellegrino. Abstract: This short note has a twofold purpose: (i) to answer a question from a recent paper of D. Popa on multilinear variants of Pietsch's composition theorem for absolutely summing operators. More precisely, we show that there is a natural (and very simple) perfect extension of Pietsch's composition theorem to the multilinear setting; (ii) to investigate extensions of some results of the aforementioned paper for particular situations, by exploring cotype properties of the spaces involved.

This is an announcement for the paper "Separable reduction theorems by the method of elementary submodels" by Marek Cuth. Abstract: We introduce an interesting method of proving separable reduction theorems - the method of elementary submodels. We are studying whether it is true that a set (function) has given property if and only if it has this property with respect to a special separable subspace, dependent only on the given set (function). We are interested in properties of sets ``to be dense, nowhere dense, meager, residual or porous'' and in properties of functions ``to be continuous, semicontinuous or Fr\'echet differentiable''. Our method of creating separable subspaces enables us to combine our results, so we easily get separable reductions of function properties such as ``be continuous on a dense subset'', ``be Fr\'echet differentiable on a residual subset'', etc. Finally, we show some applications of presented separable reduction theorems and demonstrate that some results of Zajicek, Lindenstrauss and Preiss hold in nonseparable setting as well.

2011 Workshop at A&M
by Bill Johnson 28 Jan '11

28 Jan '11

Workshop in Analysis and Probability Department of Mathematics Texas A&M University Summer 2011 The Summer 2011 Workshop in Analysis and Probability at Texas A&M University will be in session from July 5 until August 5. For information about the Workshop, consult the Workshop Home Page, whose URL is http://www.math.tamu.edu/conferences/linanalysis/ The Informal Regional Functional Analysis Seminar (SUMIRFAS) will be held July 29 - 31. Steve Dilworth, Daniel Freeman, Denka Kuzarova, Edward Odell (co-chair), and Thomas Schlumprecht (co-chair) are organizing a Concentration Week on "Greedy Algorithms in Banach spaces and Compressed Sensing" for the week of July 18-22. When encoding or reconstructing a vector using an iterative algorithm, a natural approach is to take the best or biggest approximation at each iteration. Such techniques are referred to as greedy algorithms. The theory of compressed sensing is concerned with encoding and reconstructing vectors which are sparsely represented with respect to a given basis. Kevin Ford will present a series of talks on deterministic construction of matrices with the restrictive isometry property. There will be a second series of talks devoted to greedy algorithms and bases. The home page for this Concentration Week is at http://www.math.utexas.edu/users/freeman/greedy11/index.html Florent Baudier (chair), Bill Johnson, Piotr Nowak, and Bunyamin Sari are organizing a Concentration Week on "Non-Linear Geometry of Banach Spaces, Geometric Group Theory, and Differentiability" for the week of August 1-5. The program will include an introductory course by Mark Sapir on coarse embeddings and their applications to geometric group theory, and a series of lectures by Gilles Godefroy on the recent work of the late Nigel Kalton on the coarse classification of Banach spaces. The home page for this Concentration Week is at http://www.math.tamu.edu/~pnowak/index/cw.html The Workshop is supported in part by grants from the National Science Foundation (NSF). Minorities, women, graduate students, and young researchers are especially encouraged to attend. For logistical support, including requests for support, please contact Cara Barton <cara(a)math.tamu.edu>. For more information on the Workshop itself, please contact William Johnson <johnson(a)math.tamu.edu>, David Larson <larson(a)math.tamu.edu>, Gilles Pisier <pisier(a)math.tamu.edu>, or Joel Zinn <jzinn(a)math.tamu.edu>.
