SIMIS String Math Seminar: Lax matrices and representations of shifted Yangian of gl(n) from stable envelopes

Speaker: Yehao Zhou (SIMIS)

Abstract: This is a companion talk to the one that I gave at Enumerative Geometry seminar. In this talk we focus on tripled type A quivers with potentials. We show that oscillator representations of anti-dominantly shifted Yangian of gl(n) can arise as critical cohomologies of these quiver varieties with potentials, and that their Lax matrices are constructed from stable envelops. Using coproducts of shifted Yangian, which are induced by stable envelopes, more general representations can be obtained. This talk is based on joint work in progress with Yalong Cao, Andrei Okounkov, and Zijun Zhou.

Time: Wednesday 23rd April, 4 pm

Location: Room 1610, SIMIS
