A non-linear approach to signal processing bymeans of vector measure orthogonal functions

García-Raffi, L. M.; Jiménez Fernández, Eduardo; Sánchez Pérez, Enrique Alfonso (European Mathematical Society, 2013-06)

[EN] Sequences of real functions that are orthogonal with respect to a vector measure are a natural generalization of the orthogonal systems with respect to a parametric measure. In this paper we develop a new procedure ...
Approximation of integration maps of vector measures and limit representations of Banach function spaces

Jiménez Fernández, Eduardo; Sánchez Pérez, Enrique Alfonso; Werner, Dirk (Institute of Mathematics, Polish Academy of Sciences, 2017-11-08)

[EN] We study whether or not the integration maps of vector measures can be computed as pointwise limits of their finite rank Radon¿Nikodým derivatives. The positive cases are obtained by using the circle of ideas related ...
Compactness properties of bounded subsets of spaces of vector measure integrable functions and factorization of operators

Garcia-Raffi, L. M.; Sánchez-Pérez, E.A. (Universitat Politècnica de València, 2005-10-01)

[EN] Using compactness properties of bounded subsets of spaces of vector measure integrable functions and a representation theorem for q-convex Banach lattices, we prove a domination theorem for operators between Banach ...
Extending and factorizing bounded bilinear maps defined on order continuous Banach function spaces

Calabuig Rodriguez, Jose Manuel; Fernandez Unzueta, M.; Galaz Fontes, F.; Sánchez Pérez, Enrique Alfonso (Springer, 2014-09)

We consider the problem of extending or factorizing a bounded bilinear map defined on a couple of order continuous Banach function spaces to its optimal domain, i.e. the biggest couple of Banach function spaces to which ...
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 ...
Power concave operators and representation of p-convex and q-concave Banach lattices

Delgado Garrido, Olvido; Sánchez Pérez, Enrique Alfonso (Theta Foundation, 2017)

[EN] As a consequence of the analysis of the class of (p, q)-power concave operators, we prove a general representation theorem for p-convex and q-concave Banach lattices as spaces of integrable functions with respect to ...
Strong Factorizations between Couples of Operators on Banach Function Spaces

Delgado Garrido, Olvido; Sánchez Pérez, Enrique Alfonso (Heldermann Verlag, 2013)

[EN] Let T : X1 --> Y1 and S : X2 --> Y2 be two continuous linear operators between Banach function spaces related to a finite measure space. Under some lattice requirements on the spaces involved, we give characterizations ...
Vector Measures with Values in l(infinity)(Gamma) and Interpolation of Banach Lattices

Sánchez Pérez, Enrique Alfonso; Szwedek, R. (HELDERMANN VERLAG, LANGER GRABEN 17, LEMGO, GERMANY, 32657, 2018)

[EN] An explicit construction for the representation of the Calderón interpolation of spaces of vector measure integrable functions is given as well as for the representation of the real interpolation of these spaces using ...
