Asymptotic <i>m</i>-phase soliton-type solutions of a singularly perturbed Korteweg?de Vries equation with variable coefficients. II

Abstract

We consider the problem of the construction of higher terms of asymptotic many-phase soliton-type solutions of the singular perturbed Korteweg – de Vries equation with variable coefficients. The accuracy with which the obtained asymptotic solution satisfies the original equation is determined.
