Interchanging homotopy limits and colimits in CAT [PDF]
Boletin Acad. Nac. de Ciencias, 65, (2000) 95-102, 2000 Let $I$,$J$ be small categories and $C:I\times J@>>>\CAT$ a functor to the category of small categories. We show that if $I$ has a final object then the canonical map $\operatorname{hocolim}_J\operatorname{holim}_IC@>>>\operatorname{holim}_I \operatorname{hocolim}_JC$ is a strong homotopy equivalence.

Special Holonomy Manifolds in Physics [PDF]
R. Acad. Ciencias de Zaragoza 29,(2006) 37-47 (Monograph), 2006 This is a pedagogical exposition of holonomy groups intended for physicists. After some pertinent definitions, we focus on special holonomy manifolds, two per division algebras, and comment upon several cases of interest in physics, associated with compactification from F-, M- and string theory, on manifolds of 8, 7 and 6 dimensions respectively.

Analise dinamica da tendencia para o equilibrio num modelo simples: a Segunda Lei de Newton e a Segunda Lei da Termodinamica [PDF]
Ciencia e Tecnologia dos Materiais, Vol. 14, 2/3 (2002), 2002 We relate Newton's Second Law with the Second Law of Thermodynamics through the analysis of a simple model introducing a dynamic pressure concept. From this analyses we can clarify some conceptual problems resulting from several concepts of heat and work on the First Law of Thermodynamics.

The Thermal Radiation Formula of Planck (1900) [PDF]
Rev. Academia de Ciencias, Zaragoza. 58 (2003) 91-114, 2004 We review the derivation of Planck's Radiation Formula on the light of recent studies in its centenary. We discuss specially the issue of discreteness, Planck's opinion on his discovery, and the critical analysis on the contributions by Ehrenfest, Einstein, Lorentz, etc. We also address the views of T.S.
