Gamma conjecture I for flag varieties
Chi Hong Chow
We prove Gamma conjecture I for all flag varieties by following a strategy proposed by Galkin and Iritani. The main new ingredient is showing that the totally positive part of the…
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…
The -module mirror conjecture for flag varieties
Chi Hong Chow
Rietsch constructed a candidate -equivariant mirror LG model for any flag variety . In this paper, we prove the following mirror symmetry prediction: the small $T\times\mat…
Peterson-Lam-Shimozono's theorem is an affine analogue of quantum Chevalley formula
Chi Hong Chow
We give a new proof of an unpublished result of Dale Peterson, proved by Lam and Shimozono, which identifies explicitly the structure constants, with respect to the quantum Schuber…
