题目：Criterion for a self-injective algebra to be of tilted type

　　报告人： Prof. Kunio Yamagata（Tokyo University of Agriculture and Technology）

　　摘要: By making use of a finite dimensional algebra over a field and its dual space, an infinite dimensional "self-injective" algebra without identity is defined, which is called a repetitive algebra. I will talk about some criterion theorems for a finite dimensional self-injective algebra to be obtained from a repetitive algebra.
