Shifted Quantum Affine Algebras and Relativistic Toda Systems

Since the early work of Beilinson-Bernstein, Ginzburg, Lusztig, and Nakajima, it became clear that the study of various interesting geometric moduli spaces brings better understanding towards the questions in pure representation theory. In particular, equivariant cohomology/K-theory of Nakajima quiver varieties provide a natural model for the action of the infinite-dimensional quantum groups.


In this talk, I will speak about shifted quantum affine algebras, their incarnation through the geometry of parabolic Laumon spaces and Coulomb branches, as well as their deep relation to a new family of integrable systems, generalizing the q-Toda systems of Etingof and Sevostyanov.


This talk is based on two joint works with M. Finkelberg.
