Comultiplication for shifted Yangians and quantum open Toda lattice

Advances in Mathematics. 2018. Vol. 327. P. 349-389.

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.
