Abstract

Description

This paper presents the perturbation theory for the double--sine--Gordon equation. We received the system of differential equations that shows the soliton parameters modification under perturbation's influence. In particular case $λ=0$ the results of the research transform into well-known perturbation theory for the sine--Gordon equation.
