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…
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…
Symmetries of Reduced Magnetohydrodynamics
Panagiotis Koutsomitopoulos, Reese S. Lance, S. A. Yadavalli +1
Lie-symmetry methods are used to determine the symmetry group of reduced magnetohydrodynamics. This group allows for arbitrary, continuous transformations of the fields themselves,…
