Equivariant Hochschild cohomology of group algebras and relative
Andrada Pojar, Constantin-Cosmin Todea
For a finite group , acting on a finite group we find necessary conditions for which the first -equivariant Hochschild cohomology of the group algebra is non-triv…
Nontriviality of the first Hochschild cohomology of some block algebras of finite groups
C. -C. Todea
We show that for some finite group block algebras, with nontrivial defect groups, the first Hochschild cohomology is nontrivial. Along the way we obtain methods to investigate the…
Symmetric Hochschild cohomology of twisted group algebras
Tiberiu Coconet, Constantin-Cosmin Todea
We show that there is an action of the symmetric group on the Hochschild cochain complex of a twisted group algebra with coefficients in a bimodule. This allows us to define the sy…
Basic Morita equivalences and a conjecture of Sasaki for cohomology of block algebras of finite groups
C. C. Todea
We show, using basic Morita equivalences between block algebras of finite groups, that the Conjecture of H. Sasaki from [9] is true for a new class of blocks called nilpotent cover…
