Finite Morphisms Between Differentiable AlgebrasJuan Luis García ZapataDepartamento de Matemáticas, Universidad de Extremadura,06071 Badajoz - SPAIN E-mail: jgzapata@ba.unex.es Abstract: We characterize, given a morphism $A\to B$ between differentiable algebras, when $B$ is a finite $A$-module by properties of the continuous map $Y\to X$ induced between the respective spectra and properties of the fibre rings $B/\m_x B$.
