Gamma conjecture I for flag varieties
arXiv:2501.13221
Abstract
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 Rietsch mirror is mirror to the -class and contains the critical point of the superpotential that corresponds to the Perron-Frobenius eigenvalue on the A-side.
