On cohomology of saturated fusion systems and support varieties
Constantin-Cosmin Todea
In this short note we study the cohomology algebra of saturated fusion systems using finite groups which realize saturated fusion systems and Hochschild cohomology of group algebra…
Bockstein homomorphisms for Hochschild cohomology of group algebras and of block algebras of finite groups
Constantin-Cosmin Todea
We give an explicit approach for Bockstein homomorphisms of the Hochschild cohomology of a group algebra and of a block algebra of a finite group and we show some properties. To gi…
Symmetric cohomology of groups as a Mackey functor
C. C. Todea
Symmetric cohomology of groups, defined by M. Staic in [2], is similar to the way one defines the cyclic cohomology for algebras. We show that there is a well-defined restriction,…
Hochschild cohomology of fully group-graded algebras as Mackey functor
Tiberiu Coconet, Constantin-Cosmin Todea
We prove that Hochschild cohomology of a certain class of fully group-graded algebras is a Mackey functor. We use the machinery of transfer maps between the Hochschild cohomology o…
