For an inclusion B A of operator algebras we introduce the B-nil cohomology groups H n (A | B), which can be easier to compute than the standard cohomology groups H n (A). We then develop two long exact sequences, the first linking H n (A | B), H n (A) and H n (B), the second corresponding to the Ma

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.
