The Hochschild Cohomology ring of preprojective algebras of type Ln

Estefanía Andreu Juan

Published 2010-10-13, updated 2011-09-30Version 2

We compute the Hochschild Cohomology of a finite-dimensional preprojective algebra of generalized Dynkin type Ln over a field of characteristic different from 2 . In particular, we describe the ring structure of the Hochschild Cohomology ring under the Yoneda product by giving an explicit presentation by generators and relations.
