Further extended sinh-cosh and sin-cos methods and new nontraveling wave solutions of the -dimensional dispersive long wave equations.

In this paper, based on symbolic computation and the further extended sinh- cosh and sin-cos methods, families of non-travelling wave solutions of the (2+1)- dimension dispersive long wave equations are obtained. These solutions include Jacobi elliptic function solution, soliton-like solution, and so on.
