Abstract

The 2d gauged linear sigma model (GLSM) gives a UV model for quantum cohomology on a Kahler manifold X. Recently a 3d lift (N=2 supersymmetric 3d gauge theory) of this correspondence has been proposed and explored, and Givental's permutation equivariant quantum K-theory gives the IR limit. In this talk, we will explain what K-theoretic Gromov-Witten theory is, and some other relevant topics.
