Comultiplication for shifted Yangians and quantum open Toda lattice

Michael Finkelberg, Leonid Rybnikov, Kamnitzer J., Pham K., Weekes A.

We study a coproduct in type A quantum open Toda lattice in terms of a coproduct in the shifted Yangian of sl2. At the classical level this corresponds to the multiplication of scattering matrices of euclidean SU(2) monopoles. We also study coproducts for shifted Yangians for any simply-laced Lie algebra.
