Title: Shift operators and Coulomb branches
Abstract: I will explain a generalization of shift operators using Coulomb branches with matters. This gives an action of Coulomb branch algebras with matters on equivariant quantum cohomology of semiprojective varieties, generalizing previous constructions. The novelty is a reinterpretation of the (quantized) Coulomb branch algebra. This is joint work with Ki Fung Chan and Chin Hang Eddie Lam. The research to be reported in this talk was substantially supported by grants from the RGC of the Hong Kong Special Administrative Region, China (CUHK14305322, CUHK14305023 and CUHK14302524).
