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 , 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 and a -representation , there is an associated Coulomb branch algebra defined by Braverman, Fi…
3d Mirror Symmetry is Mirror Symmetry
Ki Fung Chan, Naichung Conan Leung
3d mirror symmetry is a mysterious duality for certian pairs of hyperkähler manifolds, or more generally complex symplectic manifolds/stacks. In this paper, we will describe its re…
2d Mirrors in nonabelian 3d Mirror Symmetry
Ki Fung Chan, Naichung Conan Leung
We establish a connection between (nonabelian) equivariant 2d mirror symmetry and the geometry of Coulomb branches. In the context of 3d mirror symmetry, a Hamiltonian -manifold…
