Low-order Hamiltonian operators having momentum
Jirina Vodova
We describe all fifth-order Hamiltonian operators in one dependent and one independent variable that possess the momentum, i.e., for which there exists a Hamiltonian associated wit…

The Darboux coordinates for a new family of Hamiltonian operators and linearization of associated evolution equations
Jirina Vodova
A. de Sole, V. G. Kac, and M. Wakimoto (arXiv:1004.5387) have recently introduced a new family of compatible Hamiltonian operators of the form $H^{(N,0)}=D^2\circ((1/u)\circ D)^{2n…
