Event description:

We generalize the mathematical definition of Coulomb branches of 3d N=4 SUSY quiver gauge theories. In particular, we obtain (generalized) affine Grassmannian slices of BCFG types as examples. This construction also reproduces geometrically some interesting representations of (shifted) Yangians due to Gerasimov-Kharchev-Lebedev-Oblezin. This is a joint work with Hiraku Nakajima.
