Connections between some measures of non-compactness and associated operators
(Universidad de Extremadura, 1990)
Some relationships between the Kuratowski's measure of noncompactness, the ball measure of noncompactness and the d-separation of the points of a set are studied in special classes of Banach spaces. These relations are ...

Category measures on Baire spaces
(Universitat Autònoma de Barcelona, 1990)
The purpose of this paper is to give a necessary and sufñcient condition to define a category measure on a Baire topological space. In the last section we give some examples of spaacs in these conditions.

A special type of triangulations in numerical nonlinear analysis
(Universitat de Barcelona, 1990)
To calculate the zeros of a map f : D ⊆ Rn → Rn we consider the class of triangulations of Rn so that a certain point belongs to a simplex of fixed diameter and dimension. In this paper two types of this new class of ...
