Algebra structure on the Hochschild cohomology of the ring of invariants of a Weyl algebra under a finite group
Mariano Suarez-Alvarez
Let be the -th Weyl algebra, and let $G\subset\Sp_{2n}(\C)\subset\Aut(A_n)$ be a finite group of linear automorphisms of . In this paper we compute the multiplicative…

Hochschild homology and cohomology of generalized Weyl algebras
Marco A. Farinati, Andrea L. Solotar, Mariano Suarez-Alvarez
We compute Hochschild homology and cohomology of a class of generalized Weyl algebras (for short GWA, defined by Bavula in St.Petersbourg Math. Journal 1999 4(1) pp. 71-90). Exampl…
