地 点：思源楼S713
摘 要：In this talk, I will present a proof a decomposition formula of Kazhdan-Lusztig basis for the elements in the lowest two-sided cell of an affine Weyl group. This formula can be used to determine the lowest two-sided cell. We also present a similar decomposition formula for the second lowest two-sided cell of affine Weyl group of type Bn.
