2nd ANNOUNCEMENT OF BWB 2014 First Brazilian Workshop in Geometry of Banach Spaces August 25-29, 2014 Maresias, São Paulo State, Brazil. This is the 2nd announcement for the First Brazilian Workshop in Geometry of Banach Spaces, organized by the University of São Paulo (USP), in the week August 25-29, 2014. This international conference will take place at the Beach Hotel Maresias, on the coast of São Paulo State, in Maresias. The scientific program will focus on the theory of geometry of Banach spaces, with emphasis on the following directions: linear theory of infinite dimensional spaces and its relations to Ramsey theory, homological theory and set theory; nonlinear theory; and operator theory. Registration and abstract submissions are now open on the website of conference: http://www.ime.usp.br/~banach/bwb2014/ Deadline for registration is June 30th and for abstract submission is April 30th.

Abstract of a paper by U. Caglar, M. Fradelizi, O. Guedon, J. Lehec, C. Schuett and E. M. Werner

This is an announcement for the paper "Functional versions of L_p-affine surface area and entropy" by U. Caglar, M. Fradelizi, O. Guedon, J. Lehec, C. Schuett and E. M. Werner. Abstract: In contemporary convex geometry, the rapidly developing L_p-Brunn Minkowski theory is a modern analogue of the classical Brunn Minkowski theory. A cornerstone of this theory is the L_p-affine surface area for convex bodies. Here, we introduce a functional form of this concept, for log concave and s-concave functions. We show that the new functional form is a generalization of the original L_p-affine surface area. We prove duality relations and affine isoperimetric inequalities for log concave and s-concave functions. This leads to a new inverse log-Sobolev inequality for s-concave densities.

This is an announcement for the paper "On vector-valued tent spaces and Hardy spaces associated with non-negative self-adjoint operators" by Mikko Kemppainen. Abstract: In this paper we study Hardy spaces associated with non-negative self-adjoint operators and develop their vector-valued theory. The complex interpolation scales of vector-valued tent spaces and Hardy spaces are extended to the endpoint p=1. The holomorphic functional calculus of L is also shown to be bounded on the associated Hardy space H^1_L(X). These results, along with the atomic decomposition for the aforementioned space, rely on boundedness of certain integral operators on the tent space T^1(X).

This is an announcement for the paper "An isometrically universal Banach space with a monotone Schauder" by Joanna Garbulinska - Wegrzyn. Abstract: We present an isometric version of the complementably universal Banach space $\mathcal{B}$ with a monotone Schauder basis. The space $\mathcal{B}$ is isomorphic to Pe\l czy\'nski's space with a universal basis as well as to Kadec' complementably universal space with the bounded approximation property.

This is an announcement for the paper "$H^\infty$ functional calculus and maximal inequalities for semigroups of contractions on vector-valued $L_p$-spaces" by Quanhua Xu. Abstract: Let $\{T_t\}_{t>0}$ be a strongly continuous semigroup of positive contractions on $L_p(X,\mu)$ with $1<p<\infty$. Let $E$ be a UMD Banach lattice of measurable functions on another measure space $(\Omega,\nu)$. For $f\in L_p(X; E)$ define $$\mathcal M(f)(x, \omega)=\sup_{t>0}\frac1t\Big|\int_0^tT_s(f(\cdot,\omega))(x)ds\Big|,\quad (x,\omega)\in X\times\Omega.$$ Then the following maximal ergodic inequality holds $$\big\|\mathcal M(f)\big\|_{L_p(X; E)}\lesssim \big\|f\big\|_{L_p(X; E)},\quad f\in L_p(X; E).$$ If the semigroup $\{T_t\}_{t>0}$ is additionally assumed to be analytic, then $\{T_t\}_{t>0}$ extends to an analytic semigroup on $L_p(X; E)$ and $\mathcal M(f)$ in the above inequality can be replaced by the following sectorial maximal function $$\mathcal T_\theta(f)(x, \omega)=\sup_{|{\rm arg}(z)|<\theta}\big|T_z(f(\cdot,\omega))(x)\big|$$ for some $\theta>0$. Under the latter analyticity assumption and if $E$ is a complex interpolation space between a Hilbert space and a UMD Banach space, then $\{T_t\}_{t>0}$ extends to an analytic semigroup on $L_p(X; E)$ and its negative generator has a bounded $H^\infty(\Sigma_\sigma)$ calculus for some $\sigma<\pi/2$.

This is an announcement for the paper "On near-optimal admissible meshes" by Alexander Brudnyi. Abstract: We show that every compact subset of $\mathbb C^n$ admits a near-optimal admissible mesh. We apply this result to study geometric properties of Banach spaces of traces of real polynomials on $\mathbb R^n$ to compact subsets equipped with supremum norms.
