CMSA Algebraic Geometry in String Theory: Higgs-Coulomb correspondence in abelian GLSM
CMSA GENERAL RELATIVITY SEMINAR, SEMINARS
Konstantin Aleshkin - Columbia University
We construct a certain type of Gauged Linear Sigma Model quasimap invariants that generalize the original ones and are easier to compute. Higgs-Coulomb correspondence provides identification of generating functions of our invariants with certain analytic functions that can be represented as generalized inverse Mellin transforms. Analytic continuation of these functions provides wall-crossing results for GLSM and generalizes Landau-Ginzburg/Calabi-Yau correspondence. The talk is based on a joint work in progress with Melissa Liu.
