title:       A proposal for nonabelian mirrors in two-dimensional theories
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. By applying this to
spaces realized as symplectic quotients, one can derive B-twisted
Landau-Ginzburg orbifolds whose classical physics encodes quantum
cohomology rings of those spaces. The proposal has been checked in a
variety of cases, but for sake of time the talk will focus on exploring the
proposal in the special case of Grassmannians.
