A new Jacobi elliptic function rational expansion method and its application to (1+ 1)-dimensional dispersive long wave equation

چکیده
With the aid of computerized symbolic computation, a new elliptic function rational expansion method is presented by means of a new general ans€atz and is very powerful to uniformly construct more new exact doubly-periodic solutions in terms of rational formal Jacobi elliptic function of nonlinear evolution equations (NLEEs). As an application of the method, we choose a (1+ 1)-dimensional dispersive long wave equation to illustrate the method. As a result, we can successfully obtain the solutions found by most existing Jacobi elliptic function methods and find other new and more general solutions at the same time. Of course, more shock wave solutions or solitary wave solutions can be gotten at their limit condition. 2004 Elsevier Ltd. All rights reserved.
