Title: Hochschild Cohomology of Algebras of Quaternion Type. IV: Cohomology Algebra for Exceptional Local Algebras.
Authors: Generalov, A. I.; Semenov, V.
Abstract: The description of the Hochschild cohomology algebra for a family of local algebras of quaternion type is given in terms of generators and relations. This family appears in the famous K. Erdmann's classification only in the case where the characteristic of the base field is equal to 2.
