Virtual cycles of stable (quasi)-maps with fields

Algebraic Geometry 2021-07-20 v2

Abstract

We generalize the results of Chang-Li, Kim-Oh and Chang-Li on the moduli of pp-fields to the setting of (quasi-)maps to complete intersections in arbitrary smooth Deligne-Mumford stacks with projective coarse moduli. In particular, we show that the virtual cycle of stable (quasi-)maps to a complete intersection can be recovered by the cosection localized virtual cycle of the moduli of pp-fields of the ambient space.
