Title: Stable maps with p-fields

Abstract:

The moduli space of stable maps with p-fields was first introduced by Huai-liang Chang and Jun Li to study the higher genus Gromov-Witten invariants of the quintic threefold, and has since seen various generalizations. The goal is to study stable maps to a target Z which is not toric and does not naturally lend itself to virtual localization techniques. If Z can be realized as a vanishing locus in some space X, stable maps to Z can be related to maps with p-fields to X. In this talk, I will discuss the moduli of stable maps with p-fields on a smooth projective variety X.
