Symmetric quiver varieties and critical stable envelopes
Yalong Cao, Andrei Okounkov, Yehao Zhou +1
Symmetric quiver varieties with potentials are natural generalizations of Nakajima quiver varieties, and their equivariant critical cohomologies provide more flexible settings for…

Shifted quantum groups via critical stable envelopes
Yalong Cao, Andrei Okounkov, Yehao Zhou +1
Given a symmetric quiver with potential, we develop a geometric construction of shifted Yangians acting on the critical cohomologies of antidominantly framed quiver varieties with…
