We study the Hochschild cohomology of a finite-dimensional preprojective algebra; this is periodic by a result of A. Schofield. We determine the ring structure of the Hochschild cohomology ring given by the Yoneda product. As a result we obtain an explicit presentation by generators and relations.
We study the Hochschild cohomology of a finite-dimensional preprojective algebra โณ; this is periodic by a result of Schofield. In particular, for โณ of type A , n we obtain the dimensions and explicit characterizations and bases for all Hochschild cohomology groups.
