Darboux transformations and related non-Abelian integrable differential-difference systems of the derivative nonlinear Schrödinger type
Edoardo Peroni, Jing Ping Wang
We construct linear and quadratic Darboux matrices compatible with the reduction group of the Lax operator for each of the seven known non-Abelian derivative nonlinear Schrödinger…

Hamiltonian and recursion operators for a discrete analogue of the Kaup-Kupershmidt equation
Edoardo Peroni, Jing Ping Wang
In this paper we study the algebraic properties of a new integrable differential-difference equation. This equation can be seen as a deformation of the modified Narita-Itoh-Bogoyav…
