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…

Vertex functions of type Nakajima quiver varieties
Hunter Dinkins, Jiwu Jang
We study the quasimap vertex functions of type Nakajima quiver varieties. When the quiver varieties have isolated torus fixed points, we compute the coefficients of the vertex…
