Stable unital basis, hyperfocal subalgebras and basic Morita equivalences

Tiberiu Coconet, Constantin-Cosmin Todea

We investigate Conjecture 1.6 introduced by Barker and Gelvin in [3], which says that any source algebra of a p-block (p is a prime) of finite group has the unit group containing a…

Hochschild cohomology of some finite category algebras as simplicial cohomology

I. -I. Simion, C. -C. Todea

By a result of Gerstenhaber and Schack the simplicial cohomology ring $H^{*} (C; k)$ of a poset $C$ is isomorphic to the Hochschild cohomology ring $HH^*(k\mathcal{…

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,…
