A note on the homotopical characterization of Rn
(Universitat de Barcelona, 1992)This note gives conditions which assure that the one-point compactification of an open manifold is a manifold. This result is used to show that the homotopical characterization of Rn (n ≥ 4) can be derived from the Poincaré Conjecture.

Approximation axiomatique à la théorie du bordisme
(Université de Picardie Jules Verne, 1989)This paper gives an axiomatical approximation to Bordism Theory. It proves those properties of a geometrical nature that a class of models must satisfy to develop a bordism theory in an abstract category.

Un ejemplo de teoría de bordismo equivalente al PL-bordismo
(Academia de Ciencias Exactas, Físicas, Químicas y Naturales de Zaragoza, 1983)In this paper we define the CPL-manifolds and we prove, by using a desingularization procedure, that these objects give a ...
