Kunio Yamagata (Tokyo University of Agriculture and Technology), On triviality of symmetric Hochschild extension algebras.

Abstract:
I will talk about a classical problem that when a self-injective algebra is isomorphic to the trivial extension algebra of an algebra by a duality bimodule. An answer will be given for some class of symmetric algebras and applied to show an example of symmetric algebras.
