Abstract of a paper by Elisabeth M. Werner and Turkay Yolcu

This is an announcement for the paper "Equality characterization and stability for entropy inequalities" by Elisabeth M. Werner and Turkay Yolcu. Abstract: We characterize the equality case in a recently established entropy inequality. To do so, we show that characterization of equality is equivalent to uniqueness of the solution of a certain Monge Ampere differential equation. We prove the uniqueness of the solution using methods from mass transport, due to Brenier, and Gangbo-McCann. We then give stability versions for this entropy inequality, as well as for a reverse log Sobolev inequality and for the L_p-affine isoperimetric inequalities for both, log concave functions and convex bodies. In the case of convex bodies such stability results have only been known in all dimensions for p=1 and for p > 1 only for 0-symmetric bodies in the plane.

Abstract of a paper by Paolo Dulio, Richard J. Gardner and Carla Peri

This is an announcement for the paper "Characterizing the dual mixed volume via additive functionals" by Paolo Dulio, Richard J. Gardner and Carla Peri. Abstract: Integral representations are obtained of positive additive functionals on finite products of the space of continuous functions (or of bounded Borel functions) on a compact Hausdorff space. These are shown to yield characterizations of the dual mixed volume, the fundamental concept in the dual Brunn-Minkowski theory. The characterizations are shown to be best possible in the sense that none of the assumptions can be omitted. The results obtained are in the spirit of a similar characterization of the mixed volume in the classical Brunn-Minkowski theory, obtained recently by Milman and Schneider, but the methods employed are completely different.

This is an announcement for the paper "A remark on the diameter of random sections of convex bodies" by Shahar Mendelson. Abstract: We obtain a new upper estimate on the Euclidean diameter of the intersection of the kernel of a random matrix with iid rows with a given convex body. The proof is based on a small-ball argument rather than on concentration and thus the estimate holds for relatively general matrix ensembles.

This is an announcement for the paper "Perturbations of frames" by Dongyang Chen, Lei Li and Bentuo Zheng. Abstract: In this paper, we give some sufficient conditions under which perturbations preserve Hilbert frames and near-Riesz bases. Similar results are also extended to frame sequences, Riesz sequences and Schauder frames. It is worth mentioning that some of our perturbation conditions are quite different from those used in the previous literatures on this topic.

This is an announcement for the paper "Adaptive deterministic dyadic grids on spaces of homogeneous type" by R. Lechner and M. Passenbrunner. Abstract: In the context of spaces of homogeneous type, we develop a method to deterministically construct dyadic grids, specifically adapted to a given combinatorial situation. This method is used to estimate vector--valued operators rearranging martingale difference sequences such as the Haar system.

This is an announcement for the paper "On the equivalence of modes of convergence for log-concave measures" by Elizabeth S. Meckes and Mark W. Meckes. Abstract: An important theme in recent work in asymptotic geometric analysis is that many classical implications between different types of geometric or functional inequalities can be reversed in the presence of convexity assumptions. In this note, we explore the extent to which different notions of distance between probability measures are comparable for log-concave distributions. Our results imply that weak convergence of isotropic log-concave distributions is equivalent to convergence in total variation, and is further equivalent to convergence in relative entropy when the limit measure is Gaussian.

This is an announcement for the paper "On the existence of 1-separated sequences on the unit ball of a finite dimensional Banach space" by Eytyhios Glakousakis and Sophocles Mercourakis. Abstract: Given a finite dimensional Banach space X with dimX = n and an Auerbach basis of X, it is proved that: there exists a set D of n + 1 linear combinations (with coordinates 0, -1, +1) of the members of the basis, so that each pair of different elements of D have distance greater than one.

This is an announcement for the paper "Some characterizations of almost limited sets and applications" by N. Machrafi, A. Elbour, and M. Moussa. Abstract: Recently, J.X. Chen et al. introduced and studied the class of almost limited sets in Banach lattices. In this paper we establish some characterizations of almost limited sets in Banach lattices (resp. wDP* property of Banach lattices), that generalize some results obtained by J.X. Chen et al.. Also, we introduce and study the class of the almost limited operators, which maps the closed unit bull of a Banach space to an almost limited subset of a Banach lattice. Some results about the relationship between the class of almost limited operators and that of L-weakly compact (resp. M-weakly compact, resp. compact) operators are presented.
