## Anton Zeitlin (Columbia University) “Geometry of Bethe Equations and q-Opers”

Abstract: Integrable models are known to keep reemerging over time in various mathematical incarnations. Recently, such models based on quantum groups naturally appeared in the framework of enumerative geometry. In this context the so-called Bethe ansatz equations, instrumental for finding the spectrum of the XXZ model Hamiltonian, naturally show up as constraints for the quantum K-theory ring of quiver varieties. … Read More
