Integrals of stable envelopes for cotangent bundles to Grassmannians
Matthew Crawford, Pavan Kartik, Reese Lance
We consider cohomological stable envelopes for a natural torus action on , introduced by Maulik-Okounkov. We define the -equivariant…

Slant sums of quiver gauge theories
Hunter Dinkins, Vasily Krylov, Reese Lance
We define the slant sum of quiver gauge theories, a gluing on the underlying quivers that identifies a gauge vertex with a framing vertex. Under some mild assumptions, we relate to…

Quantum Difference Equations for Grassmannians
Xingyu Cheng, Reese Lance, Nikhil Nagabandi +1
We consider quantum difference equation (QDE) for equivariant quantum K-theory of the Grassmannian. In this paper we obtain a solution to the QDE and use the solution to asymptotic…
