Place:	Seminar Room A

Title: Moduli spaces in gauged linear sigma model (GLSM)

Abstract: Gauged linear sigma model (GLSM) is a 2d quantum field theory
invented by Witten in early 90's to give a physical derivation of 
Landau-Ginzburg (LG)/Calabi-Yau (CY) correspondence. Since then, it has
been investigated extensive in physics by Hori and others. Recently, an GLSM
algebraic-geometric theory has been formulated by Fan-Jarvis-Ruan so that
we can start to rigorously compute its invariants and match with physical 
predication. The core of this mathematical theory are certain curve-counting
moduli spaces. In this lecture, we will slowly build up these moduli spaces.
We will start from the moduli space of curves, then curves with line bundle, ... and 
so on.
