Iwahori-Coulomb branches, stable envelopes, and quantum cohomology of cotangent bundles of flag varieties

Ki Fung Chan, Kwokwai Chan, Chi Hong Chow +1

We consider Iwahori-Coulomb branches $A_{G, N, V}^{Fl}$ , which are the affine flag analogs of the original Coulomb branches $\mathcal{A}_{G,\math…

Quantum cohomology, shift operators, and Coulomb branches

Ki Fung Chan, Kwokwai Chan, Chin Hang Eddie Lam

Given a complex reductive group $G$ and a $G$ -representation $N$ , there is an associated Coulomb branch algebra $A_{G, N}^{ℏ}$ defined by Braverman, Fi…
