Localization on twisted spheres in two-dimensional gauge theories
Abstract:- I will revisit the A-twisted gauged linear sigma model (GLSM) in the case of (2,2) supersymmetry in two dimensions, together with its Omega-background deformation. Exact results for correlation functions can be obtained in terms of residues on the Coulomb branch, which has a number of interesting applications. I will also consider the generalization to (0,2) supersymmetric GLSM.
