DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/38/
 ">Intersection numbers and symmetric polynomials</a>\nby Xiaobo Liu (Pekin
 g University) as part of Algebra and Geometry Seminar @ HKUST\n\nLecture h
 eld in 4503.\n\nAbstract\nGenerating functions of intersection numbers on 
 moduli spaces of curves provide geometric solutions to integrable systems.
  Notable examples are the Kontsevich-Witten tau function and Brezin-Gross-
 Witten tau function. In this talk I will first describe how to use Schur's
  Q-polynomials to obtain simple formulas for these functions. I will then 
 discuss possible extensions for more general geometric models using Hall-L
 ittlewood polynomials. This talk is based on joint works with Chenglang Ya
 ng.\n
