HOCHSCHILD COHOMOLOGY FOR SELF-INJECTIVE ALGEBRAS OF TREE CLASS D_n. II

摘要

The minimal projective bimodule resolution for a certain family of representation-finite self-injective algebras of tree class D_n is constructed. The dimensions of the groups of Hochschild cohomology for the algebras under consideration are calculated by the instrumentality of this resolution. The resolution constructed is periodic, and accordingly the Hochschild cohomology for these algebras is periodic as well.
