On a unified study of relative Chebyshev radii and Hausdorff measures of noncompactness
(University of Houston, 2004)
The paper is concerned with the notion of the Lifschitz modulus and its relationship with both relative Chebyshev radii and Hausdorff measures of noncompactness.

Monsters in Hardy and Bergman spaces
(Taylor & Francis, 2002)
A monster in the sense of Luh is a holomorphic function on a simply connected domain in the complex plane such that it and all its derivatives and antiderivatives exhibit an extremely wild behaviour near the boundary. In ...

Fixed point property for general topologies in some Banach spaces
(Cambridge University Press, 2004)
We study the fixed point property with respect to general vector topologies in L-embedded Banach spaces. Considering a class of topologies in l1 such that the standard basis is convergent, we characterize those of them ...

Universality of holomorphic functions bounded on closed sets
(Elsevier, 2006-03-01)
In this note, the existence of translation-universal entire functions which are bounded on certain closed subsets is characterized in terms of topological and geometrical properties of such subsets. Corresponding results ...

Mellin transforms for some families of q-polynomials
(Elsevier, 2003-04-01)
By using Ramanujan's q-extension of the Euler integral representation for the gamma function, we derive the Mellin integral transforms for the families of the discrete q-Hermite II, the Al-Salam–Carlitz II, the big q-Laguerre, ...

Universal transforms of the geometric series under generalized Riesz methods
(Springer, 2004-03)
In this paper generalized Riesz methods (R, p, M) of summability are considered. We prove that, to each open set O ⊂ C with adequate topological properties and each sequence {Pn} ⊂ C tending to infinity, we can associate ...

Matrices de Jacobi, fracciones continuas vectoriales y productos de Sobolev
(2002)
La tesis doctoral se enmarca dentro de la teoría de la aproximación estudiándose tres problemas aparentemente disconexos: las matrices de Jacobi, las fracciones continuas y polinomios otorgonales respecto a productos de ...
