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…

Fusions and Clifford extensions

Tiberiu Coconet, Andrei Marcus, Constantin-Cosmin Todea

We introduce $G ˉ$ -fusions of local pointed groups on a block extension $A = b O G$ , where $H$ is a normal subgroup of the finite group $G$ , $G ˉ = G / H$ , and $b$ is a $G$ …

Block extensions, local categories, and basic Morita equivalences

Tiberiu Coconet, Andrei Marcus, Constantin-Cosmin Todea

Let $(K, O, k)$ be a $p$ -modular system with $k$ algebraically closed, let $b$ be a block of the normal subgroup $H$ of $G$ having defect pointed group $Q_{δ}$ in $…

Remarks on the extended Brauer quotient

Tiberiu Coconet, Andrei Marcus

We point out the graded structure of the extended Brauer quotient an interior $G$ -algebra.
