The moduli space in the gauged linear sigma model

Abstract

This is a survey article for the mathematical theory of Witten’s Gauged Linear Sigma Model, as developed recently by the authors. Instead of developing the theory in the most general setting, in this paper the authors focus on the description of the moduli.

Keywords
