摘要
We apply the direct perturbation method to an integrable nonlinear Schrodinger equation with a correction term to obtain its asymptotic solutions. It is shown that, there is a good qualitative agreement between the asymptotic and the exact solutions when epsilon is small enough. Then the direct perturbation method is applied to the perturbed N-component nonlinear Schrodinger equations and their asymptotical solutions are obtained.
