Gauged Linear Sigma Model is raised by E. Witten to connect CY-LG theory and used in Hori-Vafa proof for g=0 mirror symmetry. It becomes a program to construct the GLSM theory and mirror symmetry proof for all genus in mathematics, hopefully in algebraic geometry. We will introduce a LG type theory named GSW model in GLSM program that gives one step forward in this GLSM program. I will discuss a bit about the link between GSW model and the computation of g=1 GW invariant of quintic Calabi Yau threefold.
