Hochschild cohomology of a smash product in the nonsemisimple case

This will be a talk on a joint work with Yury Volkov.
We explore the relations between the Hochschild cohomology of an algebra over some field and the Hochschild cohomology of its smash product with a finite group. Basically we are concentrated on the case where the group under consideration is an extension of a cyclic $p$-group by some $p'$-group, where $p$ is the characteristic of the ground field.

Homological invariants relating the super Jordan plane to the Virasoro algebra

This will be a talk on a joint work with Sebastian Reca.
We study homological invariants of the super Jordan plane, that is, the Nichols algebra A = B(V(-1, 2)). These invariants are Hochschild homology, the Hochschild cohomology algebra, the Lie structure of the first cohomology space - which is a Lie subalgebra of the Virasoro algebra - and its representations H^n(A, A) and also the Yoneda algebra. Moreover, we prove that the Yoneda algebra of its bosonization A#kZ is finitely generated.
