Skew category algebras, twisted tensor product algebras and induction of precosheaves
Tiberiu Coconet, Virgilius-Aurelian Minuta, Constantin-Cosmin Todea
We show that a skew category algebra can be embedded into a twisted tensor product algebra. We investigate the extension of some concepts of Puig and Turull from group algebras to…

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…
