Projective tensor products where every element is norm-attaining

LC García-Lirola, J Guerrero-Viu, AR Zoca - arXiv preprint arXiv …, 2024 - arxiv.org
In this paper we analyse when every element of $ X\widehat {\otimes} _\pi Y $ attains its
projective norm. We prove that this is the case if $ X $ is the dual of a subspace of a predual …

On norm-attainment in (symmetric) tensor products

S Dantas, LC García-Lirola, M Jung… - Quaestiones …, 2023 - Taylor & Francis
In this paper, we introduce a concept of norm-attainment in the projective symmetric tensor
product of a Banach space X, which turns out to be naturally related to the classical norm …

Daugavet property of Banach algebras of holomorphic functions and norm-attaining holomorphic functions

M Jung - Advances in Mathematics, 2023 - Elsevier
We show that the duals of Banach algebras of scalar-valued bounded holomorphic functions
on the open unit ball BE of a Banach space E lack weak⁎-strongly exposed points …

Some Bishop–Phelps–Bollobás type properties in Banach spaces with respect to minimum norm of bounded linear operators

US Chakraborty - Annals of Functional Analysis, 2021 - Springer
In this paper, we study a Bishop–Phelps–Bollobás type property called the property L o, o of
a pair of Banach spaces. Getting motivated by this, we introduce the notion of Approximate …

On the strong subdifferentiability of the homogeneous polynomials and (symmetric) tensor products

S Dantas, M Jung, M Mazzitelli… - arXiv preprint arXiv …, 2022 - arxiv.org
In this paper, we study the (uniform) strong subdifferentiability of the norms of the Banach
spaces $\mathcal {P}(^ NX, Y^*) $, $ X\hat {\otimes} _\pi\cdots\hat {\otimes} _\pi X $ and $\hat …

Several Remarks on Norm Attainment in Tensor Product Spaces

AR Zoca - Mediterranean Journal of Mathematics, 2023 - Springer
The aim of this note is to obtain results about when the norm of a projective tensor product is
strongly subdifferentiable. We prove that if X⊗^ π Y is strongly subdifferentiable and either X …

New examples of strongly subdifferentiable projective tensor products

AR Zoca - arXiv preprint arXiv:2409.16286, 2024 - arxiv.org
We prove that the norm of $ X\widehat {\otimes} _\pi Y $ is SSD if either $ X=\ell_p (I) $ for $
p> 2$ and $ Y $ is a finite-dimensional Banach space such that the modulus of convexity is …

Maximal ideals of generalized summing linear operators

G Botelho, JR Campos, L Nascimento - Mediterranean Journal of …, 2024 - Springer
We prove when a Banach ideal of linear operators defined, or characterized, by the
transformation of vector-valued sequences is maximal. Known results are recovered as …

Weakening of a local Bollobás type property and geometry of Banach spaces

US Chakraborty - Acta Scientiarum Mathematicarum, 2024 - Springer
This paper deals with a weaker form of the property so called L o, o for operators, which we
call the property weak L o, o for operators. We characterize this property in terms of …
