Abstract
Let G be a finite group; our main purpose is to study the group algebra OG; actually, all the tools we are introducing are devoted to the analysis of this G-interior algebra. Note that OG is a symmetric O-algebra; more precisely, denote by v G : OG → O the O-module homomorphism fulfilling v G (x) = δ 1, x for any x ∈ G; for any idempotents i, i′ of OG, we have an O-module homomorphism
