Title: Basic Morita equivalences and a conjecture of Sasaki for cohomology of block algebras of finite groups

Autor: C.C. Todea;   


Abstract: 

We show, using basic Morita equivalences between block algebras of
nite groups, that the Conjecture of H. Sasaki from [9] is true for a new
class of blocks called nilpotent covered blocks. When this Conjecture is
true we define some transfer maps between cohomology of block algebras
and we analyze them through transfer maps between Hochschild cohomol-
ogy algebras.
