Abstract

Let Λ be an algebra over an algebraically closed field. In this paper we study about the open condition on the collection of all Λ-homomorphisms from Λ-module M to Λ-module N and on the collection of variety of complexes. Moreover, we show that the function of rank and the function of dimension of homology are lower and upper semi continuous, respectively
