题 目： Indecomposable self-injective Hochschild extension algebras
报告人： Prof. Dr. Kunio Yamagata (Tokyo University of Agriculture and Technology, Japan)
摘要：
Let A be a finite dimensional algebra over a field K. Hochschild extension algebras of A by a duality A-bimodule are self-injective.If A is indecomposable (connected), then any those Hochschild extension algebras are indecomposable, but the converse is not true in general.I will explain when Hochschild extension algebras are indecomposable and Frobenius. This is from a joint work with A. Skowronski.
