Self-improving estimates of growth of subharmonic and analytic functions

Glenier Bello, Dmitry Yakubovich

Given a bounded open subset $I^c ◯$ and closed subsets $A, B$ of $R^{k}$ , we discuss when an estimate $u (x) \leq g (d i s t (x, A \cup B))$ , $x \in I^c ◯ ∖ (A \cup B)$ , for a function $u…

On the basic sequence structure of variable exponent Lebesgue spaces

JosÃ© L. Ansorena, Glenier Bello

We study the subsymmetric basic sequence structure of variable exponent Lebesgue spaces $L_{P}$ built from index functions $P : I^c ◯ \to (0, \infty]$ on $I ¨ $ -finite measure spaces $(…

Mutually non isomorphic mixed-norm Lebesgue spaces

JosÃ© L. Ansorena, Glenier Bello

We prove that for $1 \leq p, q \leq \infty$ the mixed-norm spaces $L_{q} (L_{p})$ are mutually non-isomorphic, with the only exception that $L_{q} (L_{2})$ is isomorphic to $L_{q} (L_{q})$ for all $1<q…

Resolvent estimates for a function of a linear operator

Glenier Bello, Dmitry Yakubovich

Let $T$ be a bounded linear operator on a Banach space and $f$ an analytic function, defined on the spectrum of $T$ . We study the relations between the rate of growth of the resolv…

Embeddability of $ℓ_{p}$ -spaces into mixed-norm Lebesgue spaces in connection with the validity of vector-valued extensions of the Riesz--Fischer Theorem

The aim of this paper is twofold. On the one hand, we compute, in terms of $r$ and $s$ , the indices $p$ for which $ℓ_{p}$ isomorphically embeds into the mixed-norm separable space…
