Hochschild cohomology ring for self-injective algebras of tree class $E_6$. II (1810.03950v1)

Abstract: We describe the Hochschild cohomology ring for a family of self-injective algebras of tree class $E_6$ in terms of generators and relations. Together with the results of the previous paper, this gives a complete description of the Hochschild cohomology ring for a self-injective algebras of tree class $E_6$.
