On solvability of the first Hochschild cohomology of odd p-groups
Matthew Antrobus
We give a necessary and sufficient criterion for the solvability of as a Lie algebra, where is a -group with odd, in terms of a directed graph…

BV structure on the Hochschild cohomology of twisted tensor products
Matthew Antrobus
Given two Frobenius algebras, we describe the BV operator on the Hochschild cohomology of their tensor product twisted by a bicharacter in terms of twisted BV operators on summands…
