2018 Workshop in Analysis and Probability

Begin forwarded message: From: cara <cara(a)math.tamu.edu<mailto:cara@math.tamu.edu>> Subject: 2018 Workshop in Analysis and Probability Date: June 14, 2018 at 2:47:52 PM CDT To: undisclosed-recipients:; Workshop in Analysis and Probability Department of Mathematics Texas A&M University Summer 2018 The Summer 2018 Workshop in Analysis and Probability at Texas A&M University will be in session from July 2 to August 19. All activities will take place in the Blocker Building. The homepage of the Workshop can be found at http://www.math.tamu.edu/~kerr/workshop<http://www.math.tamu.edu/%7Ekerr/workshop> The Summer Informal Regional Functional Analysis Seminar (SUMIRFAS) will be held August 17-19. Its homepage is located at http://www.math.tamu.edu/~kerr/workshop/sumirfas2018<http://www.math.tamu.edu/%7Ekerr/workshop/sumirfas2017> August 13-17 there will be a Concentration Week, "Random Walks in Correlated and Dynamic Environments", organized by Eviatar Procaccia and Ron Rosenthal. In recent years great strides have been made in the understanding of random walks in environments more general than the i.i.d. static ones that have been the typical focus of classical investigations. A variety of new developments have spawned a host of open problems, and the time is ripe both for the community to meet and advance the theory and for a new generation of researchers to join the field. To this end, the Concentration Week will provide participants a broad exposure to ideas at the forefront of current research. Given the fact that many of the existing results apply to certain classes of random environments, a particular aim of the meeting will be to promote the search for a more universal understanding of various phenomena across these classes by bringing together specialists working in different subdisciplines. The homepage of the Concentration Week is located at https://sites.google.com/site/rwrecw<http://www.math.tamu.edu/%7Ekerr/etoa2017> 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 Starmer <cara(a)math.tamu.edu><mailto:cara@math.tamu.edu>.

Abstract of a paper by F. Bayart, D. Pellegrino, P. Rueda

This is an announcement for the paper “On coincidence results for summing multilinear operators: interpolation, $\ell_1$-spaces and cotype” by F. Bayart<https://arxiv.org/search?searchtype=author&query=Bayart%2C+F>, D. Pellegrino<https://arxiv.org/search?searchtype=author&query=Pellegrino%2C+D>, P. Rueda<https://arxiv.org/search?searchtype=author&query=Rueda%2C+P>. Abstract: Grothendieck's theorem asserts that every continuous linear operator from $\ell_1$ to $\ell_2$ is absolutely $(1,1)$-summing. This kind of result is commonly called coincidence result. In this paper we investigate coincidence results in the multilinear setting, showing how the cotype of the spaces involved affect such results. The special role played by $\ell_1$ spaces is also investigated with relation to interpolation of tensor products. In particular, an open problem on the interpolation of $m$ injective tensor products is solved. The paper may be downloaded from the archive by web browser from URL https://arxiv.org/abs/1805.12500

This is an announcement for the paper “Characterizations of almost greedy and partially greedy bases” by S. J. Dilworth<https://arxiv.org/search?searchtype=author&query=Dilworth%2C+S+J>, Divya Khurana<https://arxiv.org/search?searchtype=author&query=Khurana%2C+D>. Abstract: We shall present new characterizations of partially greedy and almost greedy bases. A new class of basis (which we call reverse partially greedy basis) arises naturally from these characterizations of partially greedy bases. We also give characterizations for $1$-partially greedy and $1$-reverse partially greedy bases. The paper may be downloaded from the archive by web browser from URL https://arxiv.org/abs/1805.06778

This is an announcement for the paper “Geometry of Orlicz spaces equipped with norms generated by some lattice norms in $\mathbb{R}^{2}$” by Yunan Cui<https://arxiv.org/search?searchtype=author&query=Cui%2C+Y>, Henryk Hudzik<https://arxiv.org/search?searchtype=author&query=Hudzik%2C+H>, Haifeng Ma<https://arxiv.org/search?searchtype=author&query=Ma%2C+H>. Abstract: In Orlicz spaces generated by convex Orlicz functions a family of norms generated by some lattice norms in $\mathbb{R}^{2}$ are defined and studied. This family of norms includes the family of the p-Amemiya norms ($1\leq p\leq\infty$) studied in [10-11], [14-15] and [20]. Criteria for strict monotonicity, lower and upper local uniform monotonicities and uniform monotonicities of Orlicz spaces and their subspaces of order continuous elements, equipped with these norms, are given in terms of the generating Orlicz functions, and the lattice norm in $\mathbb{R}^{2}$. The problems of strict convexity and of the existence of order almost isometric as well as of order isometric copies in these spaces are also discussed.

This is an announcement for the paper “Sequence Lorentz spaces and their geometric structure” by Maciej Ciesielski<https://arxiv.org/search?searchtype=author&query=Ciesielski%2C+M>, Grzegorz Lewicki<https://arxiv.org/search?searchtype=author&query=Lewicki%2C+G>. Abstract: This article is dedicated to geometric structure of the Lorentz and Marcinkiewicz spaces in case of the pure atomic measure. We study complete criteria for order continuity, the Fatou property, strict monotonicity and strict convexity in the sequence Lorentz spaces $\gamma_{p,w}$. Next, we present a full characterization of extreme points of the unit ball in the sequence Lorentz space $\gamma_{1,w}$. We also establish a complete description with an isometry of the dual and predual spaces of the sequence Lorentz spaces $\gamma_{1,w}$ written in terms of the Marcinkiewicz spaces. Finally, we show a fundamental application of geometric structure of $\gamma_{1,w}$ to one-complemented subspaces of $\gamma_{1,w}$.

This is an announcement for the paper “On proximinality of subspaces of finite codimension of Banach spaces and the lineability of the set of norm-attaining functionals” by Miguel Martin<https://arxiv.org/search?searchtype=author&query=Martin%2C+M>. Abstract: We show that for every $1<n<\infty$, there exits a Banach space $X_n$ containing proximinal subspaces of codimension $n$ but no proximinal finite codimensional subspaces of higher codimension. Moreover, the set of norm-attaining functionals of $X_n$ contains $n$-dimensional subspaces, but no subspace of higher dimension. This gives a $n$-by-$n$ version of the solutions given by Read and Rmoutil to problems of Singer and Godefroy. Actually, the space $X_n$ can be found with strictly convex dual and bidual, and such that the slices of its unit ball have diameter as close to two as desired. We also deal with the existence of strongly proximinal subspaces of finite codimension, showing that for every $1<n<\infty$ and $1\leq k <n$, there is a Banach space $X_{n,k}$ containing proximinal subspaces of finite codimension up to $n$ but not higher, and containing strongly proximinal subspaces of finite codimension up to $k$ but not higher.

This is an announcement for the paper “On the coarse geometry of the James space” by Gilles Lancien<https://arxiv.org/search?searchtype=author&query=Lancien%2C+G>, Colin Petitjean<https://arxiv.org/search?searchtype=author&query=Petitjean%2C+C>, Antonín Procházka<https://arxiv.org/search?searchtype=author&query=Proch%C3%A1zka%2C+A>. Abstract: In this note we prove that Kalton's interlaced graphs do not equi-coarsely embed into the James space J. This allows us to exhibit a coarse invariant for Banach spaces, namely the non equi-coarse embeddability of this family of graphs, which is very close but different from the celebrated property Q of Kalton.
