A Darboux-Getzler theorem for scalar difference Hamiltonian operators
Matteo Casati, Jing Ping Wang
In this paper we extend to the difference case the notion of Poisson-Lichnerowicz cohomology, an object encapsulating the building blocks for the theory of deformations of Hamilton…
PreHamiltonian and Hamiltonian operators for differential-difference equations
Sylvain Carpentier, Alexander V. Mikhailov, Jing Ping Wang
In this paper we are developing a theory of rational (pseudo) difference Hamiltonian operators, focusing in particular on its algebraic aspects. We show that a pseudo--difference H…
Remarks on certain two-component systems with peakon solutions
Mike Hay, Andrew N. W. Hone, Vladimir S. Novikov +1
We consider a Lax pair found by Xia, Qiao and Zhou for a family of two-component analogues of the Camassa-Holm equation, including an arbitrary function , and show that this app…
