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.
