Intersection Theory of Hyperquot Schemes on curves
Riccardo Ontani, Shubham Sinha, Weihong Xu
We study the virtual intersection theory of Hyperquot schemes parameterizing sequences of quotient sheaves of a vector bundle on a smooth projective curve. Our results generalize t…

On Vanishing of Gromov--Witten Invariants
Igor Pak, Colleen Robichaux, Weihong Xu
We consider the decision problem of whether a particular Gromov--Witten invariant on a partial flag variety is zero. We prove that for the -pointed, genus zero invariants, this…

On an equivalence of divisors on from Gromov-Witten theory and conformal blocks
Linda Chen, Angela Gibney, Lauren Cranton Heller +3
We consider a conjecture that identifies two types of base point free divisors on . The first arises from Gromov-Witten theory of a Grassmannian. The second comes fr…
