Abstract
We shall give a description by generators and relations of the classical and stable Hochschild cohomology ring of a finite-dimensional preprojective algebra of generalized type n over a field of characteristic 2. We also compute the structure as graded modules over the respective Hochschild cohomology rings. This completes the results in [1], where that description is obtained when the base field has characteristic ≠ 2.
