Quantum singularity theory via cosection localization

Algebraic Geometry 2018-11-19 v3

Abstract

We generalize the cosection localized Gysin map to intersection homology and Borel-Moore homology, which provides us with a purely topological construction of the Fan-Jarvis-Ruan-Witten invariants and some GLSM invariants.
