Abstract

The Exp-function method is applied to the generalized Burger’s-Fisher equation and abundant exact solutions are obtained. It is shown that the method with the help of symbolic computation provides a powerful mathematical tool for solving nonlinear evolution equations.

Keywords and phrases: the generalized Burger’s-Fisher equation, the Exp-function method, the exact solutions.
