Geometric Characterization of Injective Banach Lattices

open access: yesMathematics, 2021
This is a continuation of the authors’ previous study of the geometric characterizations of the preduals of injective Banach lattices. We seek the properties of the unit ball of a Banach space which make the space isometric or isomorphic to an injective ...

Some properties of weak Banach-Saks operators [PDF]

open access: yesMathematica Bohemica, 2021
We establish necessary and sufficient conditions under which weak Banach-Saks operators are weakly compact (respectively, {\rm L}-weakly compact; respectively, {\rm M}-weakly compact).

Bishop-Phelps-Bollobás property for positive operators when the domain is L∞

open access: yesBulletin of Mathematical Sciences, 2021
We prove that the class of positive operators from L∞(μ) to Y has the Bishop-Phelps-Bollobás property for any positive measure μ, whenever Y is a uniformly monotone Banach lattice with a weak unit.

A note on the Banach lattice $c_0( \ell_2^n)$, its dual and its bidual

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2023
The main purpose of this paper is to study some geometric and topological properties of $c_0$-sum of the finite dimensional Banach lattice $\ell_2^n$, its dual and its bidual.

On the Banach lattice $$c_0$$ [PDF]

open access: yesRevista Matemática Complutense, 2020
We show that $c_0$ is not a projective Banach lattice, answering a question of B. de Pagter and A. Wickstead. On the other hand, we show that $c_0$ is complemented in the free Banach lattice generated by itself (seen as a Banach space). As a consequence, the free Banach lattice generated by $c_0$ is not projective.

Application of ${\rm (L)$ sets to some classes of operators} [PDF]

open access: yesMathematica Bohemica, 2016
The paper contains some applications of the notion of $L$ sets to several classes of operators on Banach lattices. In particular, we introduce and study the class of order ${\rm (L)$-Dunford-Pettis operators, that is, operators from a Banach space into a

Applications for Unbounded Convergences in Banach Lattices

open access: yesFractal and Fractional, 2022
Several recent papers investigated unbounded convergences in Banach lattices. The focus of this paper is to apply the results of unbounded convergence to the classical Banach lattice theory from a new perspective.

Valuations on Banach Lattices [PDF]

open access: yesInternational Mathematics Research Notices, 2018
Abstract We provide a general framework for the study of valuations on Banach lattices. This complements and expands several recent works about valuations on function spaces, including $L_p(\mu )$, Orlicz spaces, and spaces $C(K)$ of continuous functions on a compact Hausdorff space.

Banach Lattice Structures and Concavifications in Banach Spaces

open access: yesMathematics, 2020
Let ( Ω , Σ , μ ) be a finite measure space and consider a Banach function space Y ( μ ) . We say that a Banach space E is representable by Y ( μ ) if there is a continuous bijection I : Y ( μ ...
