Abstract:
Gauged linear sigma model was proposed by Witten in the early of 90's to explain the
mirror symmetry phenomenon and the CY/LG correspondence conjecture. In this lecture,
I will firstly formulate the mathematical framework of the GLSM, and then describe an
algebraic way to construct the quantum invariants of GLSM in narrow case (for general
gauge group) via quasimaps. This was a joint work with Jarvis and Ruan. Finally I will
report the recent progress in this field and related problems.
