Moduli of curves with twisted fields and desingularization of the moduli of stable maps
Series: Algebraic Geometry Seminar

Presenter: Jingchen Niu, University of Arizona

Many moduli spaces, such as the moduli of stable maps to projective spaces, possess arbitrary singularities. In this talk, I will introduce a certain type of moduli stacks, called the moduli with twisted fields, and describe their role in the desingularization of the moduli of stable maps to projective spaces in the genus 1 and 2 cases. This talk is based on a sequence of joint works with Yi Hu and Jun Li.
