BV -Structure on Hochschild Cohomology for Exceptional Local Algebras of Quaternion Type. The Case of Small Parameter
摘要
This is second paper in the series of papers about BV -structure on the Hochshild cohomology of the exceptional algebras of quaternion type from the Erdmann classification. A full description of the BV -structure of the quaternion algebras R(k, 0, d) with k = 2 is given.
