Higher-genus wall-crossing in Landau-Ginzburg theory

Algebraic Geometry 2019-04-25 v3

Abstract

For a Fermat quasi-homogeneous polynomial, we study the associated weighted Fan-Jarvis-Ruan-Witten theory with narrow insertions. We prove a wall-crossing formula in all genera via localization on a master space, which is constructed by introducing an additional tangent vector to the moduli problem. This is a Landau-Ginzburg theory analogue of the higher-genus quasi-map wall-crossing formula proved by Ciocan-Fontanine and Kim. It generalizes the genus-00 result by Ross-Ruan and the genus-11 result by Guo-Ross.
