Abstract
The soliton perturbations of the modified Korteweg de Vries equation corres ponding to different signs of the nonlinear term are studied. The first-ord er effects of perturbation on a soliton, namely, both the slow time-depende nce of the soliton parameters and first-order corrections are derived in a direct approach based on the separation of variables.
