| Abstract: | Based on homogenous balance method and auxiliary equation method,two kinds of function transformation are introduced to change a second order linear partial differential equation into a second order linear ordinary differential equation with constant coefficients.A number of exact solutions to nonlinear evolution equations are constructed by using the solutions of the ordinary differential equation.To illustrate the method,the nonlinear long wave equation is chosen to construct the new exact complex solutio... |
