Yuming Liu (Beijing Normal University), A direct construction of simple-minded systems over self-injective Nakayama algebras

Abstract:
The simple-minded systems over a self-injective Nakayama algebra are originally classified by Riedtmann (in terms of combinatorial configurations) using covering theory. Recently Chan also classified them with the connection of tilting theory. We give a direct construction of them from the stable module category point of view. This is a joint work with Jing Guo, Yu Ye and Zhen Zhang.
