Homological epimorphisms, recollements and Hochschild cohomology - with a conjecture by Snashall-Solberg in view
Reiner Hermann
We show that recollements of module categories give rise to homomorphisms between the associated Hochschild cohomology algebras which preserve the strict Gerstenhaber structure, i.…

Exact sequences, Hochschild cohomology, and the Lie module structure over the -relative center
Reiner Hermann
In this article, we present actions by central elements on Hochschild cohomology groups with arbitrary bimodule coefficients, as well as an interpretation of these actions in terms…

Monoidal categories and the Gerstenhaber bracket in Hochschild cohomology
Reiner Hermann
In this monograph, we extend S. Schwede's exact sequence interpretation of the Gerstenhaber bracket in Hochschild cohomology to certain exact and monoidal categories. Therefore we…
