摘要：Motivic Chern classes are the K-theoretical generalization of Chern--Schwartz--MacPherson classes, which also specialize to the total-classes of the cotangent bundle to singular varieties as well as some other important characteristic classes for singular varieties, such as Chern classes, Todd classes, and L-classes. In this talk, we shall introduce a Pieri formula for motivic Chern classes of Schubert cells in the equivariant K-theory of Grassmannians. This is based on joint work with Peter L. Guo、Changjian Su and Rui Xiong.
