Hamiltonians for the quantised Volterra hierarchy
Sylvain Carpentier, Alexander V. Mikhailov, Jing Ping Wang
This paper builds upon our recent work, published in Lett. Math. Phys., 112: 94, 2022, where we established that the integrable Volterra lattice on a free associative algebra and t…

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…
