Stability of solitons described by KdV-type equations with higher-order dispersion and nonlinearity (analytical results)
Abstract
Soliton stability described by KdV-type equations with higher-order dispersion and nonlinearity is studied analytically. Criterions of linear and nonlinear soliton stability and adjoining formulas are derived in a form that will guide a future study of soliton stability by means of numerical simulations.
