Abstract
Let G be a finite group; our main purpose is the study of the group algebra OG and of any 0G-module M or, equivalently, any group homomorphism G → Endo(M)*, where M is an O-free O-module. More generally, we may consider any group homomorphism G → A*, where A is an 0-algebra; for instance, whenever cp: G → Aut(B) is an action of G on an O-algebra B, the group algebra BG of G over B is the free B-module ®xEG Bx over the set G, endowed with the following product
