摘要
The Macdonald polynomials are very important symmetric functions, generalizing the Schur functions, Hall-Littlewood polynomials, etc. I will report a joint work in progress with Ion and Mihalcea, in which we define a symmetric function via the motivic Chern classes of the Schubert cells in the affine Grassmannian. These polynomials depends on two variables q and t, and enjoy very similar specializations as the Macdonald polynomials.
