Rigid local systems and the quantum cohomology of the Grassmannian
Prakash Belkale, University of North Carolina

Abstract: My aim is to describe a correspondence between rigid local systems on the projective line and Gromov-Witten invariants (these are structure coefficients of the small quantum cohomology) for the Grassmannian which evaluate to 1. This correspondence follows from the proof of a generalization of a conjecture of Fulton.
