Soliton solutions of perturbed nonlinear Schrodinger equation with Kerr law nonlinearity via the modified simple equation method and the subordinary differential equation method

Abstract

The objective of this paper was to obtain soliton solutions for a perturbed nonlinear Schrodinger equation with Kerr law nonlinearity using the modified simple equation method and subordinary differential equation method. These methods appear to be efficient and they can be applied in seeking exact solutions of many other nonlinear evolution equations encountered in science and engineering studies.
