Some geometric properties concerning fixed point theory
(Universidad Complutense de Madrid, 1996)
The Fixed Point Theory for nonexpansive mappings is strongly based upon the geometry of the ambient Banach space. In section 1 we state the role which is played by the multidimensional convexity and smoothness in this ...

The essential norm of a composition operator on Bloch spaces
(Mathematical Sciences Publishers, 1999-04)
We express the essential norm of a composition operator on the Bloch space and the little Bloch space as the asymptotic upper bound of a quantity involving the inducing map and the Pick-Schwarz Lemma. As a consequence, we ...

On the linearization problem involving Pochhammer symbols and their q-analogues
(Elsevier, 1999-07-15)
In this paper we present a simple recurrent algorithm for solving the linearization problem involving some families of q-polynomials in the exponential lattice x(s)=c1qs+c3. Some simple examples are worked out in detail.

The modification of classical Hahn polynomials of a discrete variable
(Taylor & Francis, 1995)
We consider a modi cation of moment functionals for the Hahn classical polynomials of a discrete variable by adding two mass points at the ends of the interval, i.e., in x = 0 and x = N 1. We obtain the resulting orthogonal ...

Relaciones entre operadores asociados a distintas medidas de no compacidad
(1993-09-13)
El objeto fundamental del trabajo es investigar las relaciones existentes entre operadores contractivos para distintas medidas de no compacidad en base a las propiedades geométricas del espacio subyacente, para ello se ...

Concentration of the distance in finite dimensional normed spaces
(University College London, Faculty of Mathematical and Physical Sciences, Department of Mathematics, 1998-12)
We prove that in every finite dimensional normed space, for “most” pairs (x, y) of points in the unit ball, ∥x − y∥ is more than √2(1 − ε). As a consecuence, we obtain a result proved by Bourgain, using QS-descomposition, ...
