On the quantum parameter in the quantum cohomology of a family of odd symplectic partial flag varieties

Connor Bean, Caleb Shank, Ryan M. Shifler

We will consider a particular family of odd symplectic partial flag varieties denoted by $\mbox{IF}$. In the quantum cohomology ring $\mbox{QH}^*(\mbox{IF})$, we will show that $q_…

Curve neighborhoods and combinatorial property for a family of odd symplectic partial flag manifolds

Connor Bean, Bradley Cruikshank, Ryan M. Shifler

Let be an odd dimensional complex vector space and $\mbox{IF}:=\mbox{IF}(1,2;E)$ be the family of odd symplectic partial flag manifold. In this paper we give a full description…

On the spectral properties of the quantum cohomology of odd quadrics

Ryan M. Shifler, Stephanie Warman

Let $H^\bullet(\mbox{OG})$ be the quantum cohomology (specialized at ) of the dimensional quadric $\mbox{OG}$. We will calculate the characteristic polynomial of the li…

Positivity determines the quantum cohomology of the odd symplectic Grassmannian of lines

Ryan M. Shifler

Let $\mbox{IG}:=\mbox{IG}(2,2n+1)$ denote the odd symplectic Grassmannian of lines which is a horospherical variety of Picard rank 1. The quantum cohomology ring $\mbox{QH}^*(\mbox…

Minimum quantum degrees with Maya diagrams

Ryan M. Shifler

We use Maya diagrams to refine the criterion by Fulton and Woodward for the smallest powers of the quantum parameter that occur in a product of Schubert classes in the (small)…
