题 目：Moving vectors of Ariki-Koike algebras
时 间：2023.08.08（星期二）14:00-15:00
地 点：思源楼S817
摘 要：Ariki-Koike algebras were introduced by Ariki and Koike and independently by Broué and Malle, which include Hecke algebras of types A and B as special cases. They play an important role in modular representation theory of finite groups of Lie type, and are in relation with various significant objects, such as quantum groups and rational Cherednik algebras. For a given block of an Ariki-Koike algebra, we introduced recently a new invariant, called moving vector, which can be considered as a generalization of the weight. In this talk, we will present some applications of moving vectors.

题 目：A characterization of algebras generated by idempotents
时 间：2023.08.08（星期二）15:10-16:10
地 点：思源楼S817
摘 要：This talk is based on a joint work with Wei Hu, in which we study algebras generated by idempotents. For finite dimensional algebras over a field, it turns out that these algebras can be characterized by their irreducible modules homologically. Several related open problems are also presented in this talk.
