Reduction theorems for a conjecture on basis in source algebras of blocks of finite groups

Tiberiu Coconet, Constantin-Cosmin Todea

The aim of this short research note is to present some results about a conjecture of Barker and Gelvin claiming that any source algebra of a block of a finite group has the unit gr…

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…

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…

Isomorphisms of fusion subcategories on permutation algebras

Tiberiu Coconet, Constantin-Cosmin Todea

We prove two isomorphisms of categories involving Brauer pairs on -permutation -interior -algebras.

Fusions and Clifford extensions

Tiberiu Coconet, Andrei Marcus, Constantin-Cosmin Todea

We introduce -fusions of local pointed groups on a block extension , where is a normal subgroup of the finite group , , and is a …

Block extensions, local categories, and basic Morita equivalences

Tiberiu Coconet, Andrei Marcus, Constantin-Cosmin Todea

Let be a -modular system with algebraically closed, let be a block of the normal subgroup of having defect pointed group in $…
