Title: GW theory, FJRW theory, and MSP fields
Speaker: Chiu-Chu Melissa Liu
Speaker Info: Columbia University
Brief Description:
Abstract:

Gromov-Witten (GW) invariants of the quintic Calabi-Yau 3-fold are virtual counts of stable maps to the quintic 3-fold. Fan-Jarvis-Ruan-Witten (FJRW) invariants of the Fermat quintic polynomial are virtual counts of solutions to the Witten equation associated to the Fermat quintic polynomial. In this talk, I will describe the theory of Mixed-Spin-P (MSP) fields interpolating GW theory of the quintic 3-fold and FJRW theory of the Fermat quintic polynomial, based on joint work with Huai-Liang Chang, Jun Li, and Wei-Ping Li.
