Learning Seminar 10/27

Speaker: Amanda Schwartz

Abstract: We will define and compute examples of R-polynomials, which were first introduced by Kazhdan and Lusztig. These polynomials give the point count of Richardson varieties over a finite field. We will also discuss connections between R-polynomials and HOMFLYPT polynomials.

Notes for the talk are here.
