The simplest equation method to study perturbed nonlinear Schrodinger's equation with Kerr law nonlinearity

The simplest equation method is a powerful solution method for obtaining exact solutions of nonlinear evolution equations. In this paper, the simplest equation method is used to construct exact solutions of nonlinear Schrodinger's equation and perturbed nonlinear Schrodinger's equation with Kerr law nonlinearity. It is shown that the proposed method is effective and general. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
