TL;DR: In this paper, the stability of solitons is reviewed for nonlinear conservative media and the main attention is paid to the description of the methods: perturbation theory, inverse scattering transform, Lyapunov method.

TL;DR: In this article, it was shown that using multi-scale expansions conventionally employed in the theory of nonlinear waves one can transform systems integrable by the IST method into other systems of this type.
