摘要：

In this paper, we present a method to solve nonlinear difference differential equation(s). We applied this method to quintic discrete nonlinear Schrodinger equation to illustrate this method. Many exact solutions are obtained with the help of Maple including soliton solutions presented by hyperbolic functions sinh and cosh, periodic solutions presented by sin and cos and rational solutions. This method can also be used to other nonlinear difference-differential equation(s). (c) 2006 Elsevier Ltd. All rights reserved.
