Abstract
A new direct approach based on the separation of variables for soliton pert urbations is developed. With the aid of this approach, the effects of pertu rbation on a soliton of nonlinear Schrodinger (NLS) equation is obtained. I n comparison with other direct methods, our approach is very concise and ea sy to be understood. Besides, no more approximation is employed except for the linearization of the perturbed NLS equation.
