Two Generalizations of the (G'/G)-expansion Method and their Applications to Nonlinear Evolution Equations

In this paper, two generalizations of the (G'/G)- expansion method are proposed which results more different types of exact solutions to nonlinear evolution equations. As applications, the new exact non-travelling wave solutions of the (2+1)-dimension Burger equation and the (2+1)-dimensional breaking solution equations are obtained by using two generalized (G'/G)-expansion methods.
