Department of Mathematics - Algebra and Geometry Seminar - Intersection numbers and symmetric polynomials

4:30pm - 6:00pm
Room 4503 (Lifts 25/26)

Generating 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-Littlewood polynomials. This talk is based on joint works with Chenglang Yang.
