Title : A proposal for nonabelian mirrors in two-dimensional theories
Time : 2023-01-30 (Mon) 10:00 - 12:00
Place : Auditorium, 6 Floor, Institute of Mathematics (NTU Campus)
Abstract: In this talk we will describe a proposal for nonabelian mirrors to two-dimensional (2,2) supersymmetric gauge theories, generalizing the Hori-Vafa construction for abelian gauge theories. Specifically, we will describe a construction of B-twisted Landau-Ginzburg orbifolds whose classical physics encodes Coulomb branch relations (quantum cohomology), excluded loci, and correlation functions of A-twisted gauge theories. The proposal has been checked in a wide variety of cases, but the talk will focus on exploring the proposal in two examples: Grassmannians (constructed as U(k) gauge theories with fundamental matter), and SO(2k) gauge theories.
