Modules and Cohomology over Group Algebras: One Commutative Algebraist's Perspective
arXiv:math/0409188
Abstract
This article explains basic constructions and results on group algebras and their cohomology, starting from the point of view of commutative algebra. It provides the background necessary for a novice in this subject to begin reading Dave Benson's article in the same MSRI volume that this article is slated to appear in.
