报告内容介绍：
The theory of Higgs and Coulomb branches of three-dimensional N=4 gauge theories plays a fundamental role ingeometric representation theory. For quiver gauge theories, the Higgs branches are Nakajima quiver varieties, which providegeometric constructions of integrable representations of Kac-Moody algebras. On the other side, quantized Coulombbranches can be identified with truncated shifted Yangians. 3Dmirror symmetry exchanges Higgs and Coulomb branches ofdual theories, placing these constructions within a commonframework.
In this talk, I will introduce a new class of Gauge theoriesassociated to quivers with involution. In particular, thecorresponding Coulomb branches are closely related to theshifted twisted Yangians through iGKLO homomorphisms. The talk is based on joint work with Changjian Su and RuiXiong.
