Hochschild Cohomology for Algebras of Semidihedral Type. VII. Algebras with a Small Parameter

Аннотация

The Hochschild cohomology groups are computed for algebras of semidihedral type, which are contained in the family SD(2ℬ)₂(k, t, c) (from the famous K. Erdmann’s classification) in the case where k = 1. In the calculation, the beforehand construction of the minimal bimodule resolution for algebras from the subfamily under discussion is used.
