活动主题:Invariant subalgebras of groups acting on matrix algebras
形式:线上学术报告
活动内容摘要:
Given a positive integer n and a field k, we consider an action of a group on the full n by n matrix algebra over k, and the invariant subalgebra of the action. In this talk, we show that this subalgebra has nice homological and structural properties. For example, it is a Gorenstein algebra and has the property of Frobenius extension. Moreover, it is a cellular algebra in the sense of Graham-Lehrer.
The contents of the talk are taken from joint works with Jinbi Zhang.
