AModel correlators from the Coulomb branch
Abstract
We compute the contribution of discrete Coulomb vacua to AModel correlators in toric Gauged Linear Sigma Models. For models corresponding to a compact variety, this determines the correlators at arbitrary genus. For noncompact examples, our results imply the surprising conclusion that the quantum cohomology relations break down for a subset of the correlators.
