Title: FRG Lecture Series: 3d Gauge Theory & Quantum KTheory Correspondence
Abstract: The 2d gauged linear sigma model offers a model for quantum cohomology on Kahler manifolds. In these lectures I introduce certain 3d gauge theories and demonstrate that they realize a model for Givental's permutation equivariant quantum Ktheory on Kahler manifolds. I explain that in this setup the Ktheoretic Givental's I function is encoded in suitable gauge theory partition functions. In this gauge theory/quantum Ktheory correspondence we analyze the dictionary between the gauge theory deformations and the parameters in quantum Ktheory. Then we discuss some applications such as integral BPS invariants, 3d chiral rings, and 3d mirror symmetry, which relate to questions in enumerative geometry.
