SUMMARY:The Module structure of a Group Action on a Ring - Peter Symonds (

DESCRIPTION:Consider a finite group $G$ acting on a graded Noetherian $k$-
 algebra $S$\, for some field $k$ of characteristic $p$\; for example $S$ m
 ight be a polynomial ring. Regard $S$ as a $kG$-module and consider the mu
 ltiplicity of a particular indecomposable module as a summand in each degr
 ee. We show how this can be described in terms of homological algebra and 
 how it is linked to the geometry of the group action on the spectrum of $S
 $.
