DOUBLE AFFINE GRASSMANNIANS AND COULOMB BRANCHES OF 3dN = 4 QUIVER GAUGE THEORIES
P. 1279-1298.
We propose a conjectural construction of various slices for double affine Grass-
mannians as Coulomb branches of 3-dimensional N = 4 supersymmetric affine quiver
gauge theories. It generalizes the known construction for the usual affine Grassman-
nians, and makes sense for arbitrary symmetric Kac-Mody algebras.
