Interpolation subspaces of L^1 of a vector measure and norminequalities for the integration operator

Calabuig Rodriguez, Jose Manuel; Rodríguez Ruiz, José; Sánchez Pérez, Enrique Alfonso (American Mathematical Society, 2012)

[EN] Let m be a Banach space valued measure. We study some domination properties of the integration operator that are equivalent to the existence of Banach ideals of L1(m) that are interpolation spaces. These ...
Kaplan-Meier Type Survival Curves for COVID-19: A Health Data Based Decision-Making Tool

Maximal Factorization of Operators Acting in Kothe-Bochner Spaces

Calabuig, J. M.; Fernández-Unzueta, M.; Galaz-Fontes, F.; Sánchez Pérez, Enrique Alfonso (Springer-Verlag, 2021-01)

[EN] Using some representation results for Kothe-Bochner spaces of vector valued functions by means of vector measures, we analyze the maximal extension for some classes of linear operators acting in these spaces. A ...
Multiplication operators in Kothe-Bochner spaces

Calabuig Rodriguez, Jose Manuel; Rodriguez, J.; Sánchez Pérez, Enrique Alfonso (Elsevier, 2011)

Let X be a Banach space and E an order continuous Banach function space over a finite measure mu. We prove that an operator T in the Kothe-Bochner space E(X) is a multiplication operator (by a function in L(infinity)(mu)) ...
On Completely Continuous Integration Operators of a Vector Measure

Calabuig Rodriguez, Jose Manuel; Rodríguez Ruiz, José; Sánchez Pérez, Enrique Alfonso (Heldermann Verlag, 2014)

[EN] Let m be a vector measure taking values in a Banach space X. We prove that if the integration operator Im : L1(m) -> X, is completely continuous and X is Asplund, then m has finite variation and L1(|m|) = L1(m).
On p-Dunford integrable functions with values in Banach spaces

Calabuig, J. M.; Rodríguez, J.; Rueda, P.; Sánchez Pérez, Enrique Alfonso (Elsevier, 2018-08)

[EN] Let (Omega, Sigma, mu) be a complete probability space, X a Banach space and 1 <= p < infinity. In this paper we discuss several aspects of p-Dunford in-tegrable functions f : Omega->X. Special attention is paid to ...
On the Banach lattice structure of L-w(1) of a vector measure on a delta-ring

Calabuig Rodriguez, Jose Manuel; Delgado Garrido, Olvido; Juan Blanco, María Aránzazu; Sánchez Pérez, Enrique Alfonso (Universitat de Barcelona, 2014-01)

We study some Banach lattice properties of the space L-w(1)(v) of weakly integrable functions with respect to a vector measure v defined on a delta-ring. Namely, we analyze order continuity, order density and Fatou type ...
On the smoothness of L p of a positive vector measure

Agud Albesa, Lucia; Calabuig Rodriguez, Jose Manuel; Sánchez Pérez, Enrique Alfonso (Springer Verlag (Germany), 2015-11)

We investigate natural sufficient conditions for a space L p(m) of pintegrable functions with respect to a positive vector measure to be smooth. Under some assumptions on the representation of the dual space of such a ...
Optimal extensions of compactness properties for operators on Banach function spaces

Calabuig, J. M.; Jiménez Fernández, Eduardo; Juan Blanco, María Aránzazu; Sánchez Pérez, Enrique Alfonso (Elsevier, 2016)

[EN] Compactness type properties for operators acting in Banach function spaces are not always preserved when the operator is extended to a bigger space. Moreover, it is known that there exists a maximal (weakly) compact ...
p-Variations of vector measures with respect to vector measures and integral representation of operators

Blasco de la Cruz, Oscar; Calabuig, J. M.; Sánchez Pérez, Enrique Alfonso (Duke University Press, 2015)

[EN] In this paper we provide two representation theorems for two relevant classes of operators from any p-convex order continuous Banach lattice with weak unit into a Banach space: the class of continuous operators and ...
