  • Abstract : In this talk, we discuss a generalization of shift operators on equivariant quantum cohomology to the settings of Coulomb branches of 3d gauge theories. The construction relies on a reinterpretation of the Coulomb branch, and applies for X whose fixed loci are non-compact. As an application, we give another proof of Teleman's gluing description of the Coulomb branch. This is a joint work with Kwokwai Chan and Ki Fung Chan.
