A new extended tanh-function method and its application to the dispersive long wave equations in (2+1) dimensions

摘要

In this paper, a new extended tanh-function method is suggested to constructing multiple exact solutions for nonlinear partial differential equations. The validity and reliability of the method is tested by its application to the dispersive long wave equations in (2 + 1) dimensions. More new explicit exact solutions are found.
