Title: Coulomb branches of symmetrizable quiver gauge theories

Place: Seminar Room A
Abstract: Coulomb branches of 3d N=4 SUSY quiver gauge theories for
type ADE were affine Grassmannian slices or their generalization for
the corresponding ADE group. Slices for BCFG groups were realized as
fixed point subschemes under diagram automorphisms, but they a priori do
not share nice properties of Coulomb branches. I propose a new
definition, motivated by works of Geiss, Leclerc, Schroer. The new
Coulomb branches are slices for BCFG groups in finite type, and have
the normality, existences of integrable systems, quantization, and
various nice properties. It also suggest a new way to look for the
corresponding Higgs branchs, which should be considered as quiver
varieties for symmetrizable Cartan matrices. This is a joint work
with Alex Weekes.
