SUMMARY:Injective Hulls of Trivial Modules - Jonathan Nelson (University o
 f Cambridge)

DESCRIPTION:We can model representations of abstract groups as modules of 
 the corresponding group algebra\; for example\, those of abelian groups ar
 e modules of polynomial rings in some number of variables. The homological
  properties of such modules are in part determined by the minimal injectiv
 e module containing them\, the injective hull. In this talk I shall aim to
  demystify these hulls with explicit examples in the case of abelian group
 s\, soluble groups and nilpotent p-adic groups.\n\nThis talk is an extende
 d version of the one I will give at YRM in Bristol.
