Banach spaces with the weak diametral diameter two property

Juan Guerrero-Viu, Miguel Martín, Abraham Rueda Zoca

We introduce and systematically study the weak diametral diameter two property (weak-DD2P), a new geometric property that lies strictly between the diametral diameter two property…

Functions in with optimal tensor representations

Luis C. García-Lirola, Juan Guerrero-Viu

We study the existence and characterization of optimal tensor representations of elements in the space of Bochner integrable functions. We completely describe the set of…

On super Delta-points and the convex-DLD2P in absolute sums

Juan Guerrero-Viu, Joanna Markowicz

We partially answer two open questions concerning diameter two properties in absolute sums. First, we identify the conditions that a super -point in an absolute sum of Banach sp…

Composition operators for holomorphic Lipschitz functions

Verónica Dimant, Luis C. García-Lirola, Juan Guerrero-Viu +1

We study composition operators on spaces of holomorphic Lipschitz functions defined on the open unit ball of a complex Banach space. Our approach is based on the linearization of t…

Integral representations of projective norm-attaining tensors

Ramón J. Aliaga, Sheldon Dantas, Juan Guerrero-Viu +2

We introduce a Bochner integral approach to projective norm attainment in tensor products of Banach spaces by defining the class of integral projective norm-attaining tensors. This…

Almost preserved extreme points

Ramón J. Aliaga, Luis C. García-Lirola, Juan Guerrero-Viu +2

In this paper we introduce the notion of an almost preserved extreme point (APEP) of a set as a weakening of the concept of preserved extreme points, and we systematically study su…
