Eine Bemerkung zur Stabilitat von Entfaltungen

Abstract

In his stability theorem on unfoldings of germs of C^∞-functions G. Wassermann has proved the equivalence of several properties of an unfolding, e. g. “infinitesimally stable” and “universal”. This paper which is close to his work adds another equivalent property. Two examples show that this property can also be considered in the context of other stability theorems.
