The modified (G′/G)-expansion method and traveling wave solutions of nonlinear the perturbed nonlinear Schrodinger's equation with Kerr law nonlinearity

In this paper, we construct the traveling wave solutions to the perturbed nonlinear Schrodinger's equation (NLSE) with Kerr law nonlinearity by using the modified (G'/G)-expansion method. The traveling wave solutions are expressed by the hyperbolic functions, trigonometric functions and rational functions. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
