摘  要：The motivic Chern classes of the Schubert cells are the K-theoretic generalizations of the Chern-Schwartz-MacPherson classes in homology. I will report some joint work in progress with L. Mihalcea and H. Naruse about the Chevalley formula for these classes. Applications include a complete description for the Maulik-Okounkov K-theoretic stable envelopes for the Springer resolution, and computations of the Iwahori-Whittaker functions for the p-adic dual group.
