✦ Synopsis

The soliton perturbation theory is used to study the solitons that are governed by the modified nonlinear Schro ¨dinger's equation. The adiabatic parameter dynamics of the solitons in presence of the perturbation terms are obtained. In particular, the nonlinear gain (damping) and filters or the coefficient of finite conductivity are treated as perturbation terms for the solitons.
