Hamilton theory of NLS equation soliton motion
A. M. Kamchatnov
We suggest the method of derivation of Hamilton equations which describe the motion of solitons along non-uniform and time dependent large-scale background in case of wave dynamics…

Quasiclassical integrability condition in AKNS scheme
A. M. Kamchatnov, D. V. Shaykin
In this paper, we study the condition of quasiclassical integrability of soliton equations. This condition states that the Hamiltonian structure of equations, which govern propagat…
