TITLE: Symmetric bow varieties

ABSTRACT: In my joint work with Takayama, I showed that Coulomb branches of quiver gauge theories of affine type A, as defined in earlier joint work with Braverman and Finkelberg, are isomorphic to Cherkis’ bow varieties. For quiver gauge theories of affine type D, or more generally of classical affine types, we introduce symmetric bow varieties, which are fixed point loci of involution on bow varieties.
