Title : Cubic Hodge integrals and enumeration of ribbon graphs
Time : 2017-09-29 (Fri) 11:00 - 12:30
Place : Seminar Room 617, Institute of Mathematics (NTU Campus)
Abstract: We indicate and prove a relationship between special cubic Hodge integrals over the moduli space of stable algebraic curves and enumeration of ribbon graphs with even valencies. The talk is based on a series of joint works with Boris Dubrovin, Si-Qi Liu and Youjin Zhang.
