On Hochschild cohomology of preprojective algebras, I
We study the Hochschild cohomology of a finite-dimensional preprojective algebra Λ; this is periodic by a result of Schofield. In particular, for Λ of type An, we obtain the dimensions and explicit characterizations and bases for all Hochschild cohomology groups. © 1998 Academic Press.
