Description
Abstract: In this talk, I will discuss two-dimensional gauged linear sigma models realizing symplectic Grassmannians. After describing the construction of the GLSMs themselves, I will explain how the Coulomb branch computations in such GLSMs reproduce known ordinary and equivariant quantum cohomology ring relations. For the interests of string theorists, I will also discuss the Calabi-Yau condition inside symplectic Grassmannians. Similar constructions and analysis can also be used for more general isotropic spaces, for example, orthogonal Grassmannians and general isotropic flag
manifolds.
