Absolutely continuous multilinear operators

Dahia, E.; Achour, D.; Sánchez Pérez, Enrique Alfonso (Elsevier, 2013-01)

We introduce the new class of the (p;p1,...,pm; s)-absolutely continuous operators, that is defined using a summability property that provides the multilinear version of the (p, s)-absolutely continuous operators. We give ...
Compact weighted composition operators on spaces of holomorphic functions on Banach spaces

Bonet Solves, José Antonio; Jornet Casanova, David; Santacreu, Daniel; Sevilla Peris, Pablo (Theta Foundation, 2023)

[EN] Given an infinite dimensional Banach space X and its open unit ball B , we study when the weighted composition operator C ,l, ,p is compact in the space of all bounded analytic functions H & DEG;& DEG;(B) , and when ...
Composition Operators on Classes of Holomorphic Functions on Banach Spaces

Santacreu Ferra, Daniel (Universitat Politècnica de València, 2022-09-05)

[ES] El objetivo principal de esta tesis es el estudio de diferentes propiedades (principalmente ergódicas) de operadores de composición y de composición ponderados actuando en espacios de funciones holomorfas definidas ...
Factorization of operators through subspaces of L-1-spaces

Calabuig, J. M.; Rodríguez, José; Sánchez Pérez, Enrique Alfonso (Cambridge University Press, 2017-12)

[EN] We analyze domination properties and factorization of operators in Banach spaces through subspaces of L1-spaces. Using vector measure integration and extending classical arguments based on scalar integral bounds, we ...
Generalized Cesàro operators in weighted Banach spaces of analytic functions with sup-norms

Albanese, Angela A.; Bonet Solves, José Antonio; Ricker, Werner J. (Springer-Verlag, 2024-03)

[EN] An investigation is made of the generalized Cesaro operators Ct\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} ...
Mean ergodicity and spectrum of the Cesàro operator on weighted c0 spaces

Albanese, Angela A.; Bonet Solves, José Antonio; Ricker, Werner J. (Springer-Verlag, 2016)

[EN] A detailed investigation is made of the continuity, the compactness and the spectrum of the Cesàro operator C acting on the weighted Banach sequence space c0(w) for a bounded, strictly positive weight w. New features ...
Multiplier and averaging operators in the Banach spaces ces(p), 1<p< infty

Albanese, Angela A.; Bonet Solves, José Antonio; Ricker, Werner J. (Springer-Verlag, 2019-02)

[EN] The Banach sequence spaces ces(p) are generated in a specified way via the classical spaces p,1<p<. For each pair 1<p,q< the (p,q)-multiplier operators from ces(p) into ces(q) are known. We determine precisely which ...
Spectrum and compactness of the Cesàro operator on weighted l_p spaces

Albanese, Angela; Bonet Solves, José Antonio; Ricker, Werner J. (Cambridge University Press, 2015)

[EN] An investigation is made of the continuity, the compactness and the spectrum of the Ces`aro operator C when acting on the weighted Banach sequence spaces l_p(w), 1 < p < 1, for a positive decreasing weight w, thereby ...
The Cesàro operator on weighted l_1 spaces

Albanese, Angela; Bonet Solves, José Antonio; Ricker, W. (John Wiley & Sons, 2018)

[EN] Unlike for l(p), 1 < p <= infinity, the discrete Cesaro operator C does not map l(1) into itself. We identify precisely those weights w such that C does map l(1)(w) continuously into itself. For these weights a complete ...
Weighted composition operators on Korenblum type spaces of analytic functions

Gomez-Orts, Esther (Springer-Verlag, 2020-09-05)

[EN] We investigate the continuity, compactness and invertibility of weighted composition operators W-psi,W-phi: f -> psi(f circle phi) when they act on the classical Korenblum space A(-infinity) and other related Frechet ...
Weighted Composition Operators on Spaces of Analytic Functions

Gomez Orts, Esther (Universitat Politècnica de València, 2022-05-30)

[ES] El objetivo de esta tesis es estudiar distintas propiedades de los operadores de composición ponderados en diferentes espacios ponderados de funciones analíticas. Dado un peso v estrictamente positivo y continuo en ...
