Application of Heʹs exp-function method for nonlinear evolution equations

In this paper, Heʹs exp-function method is used to construct solitary and soliton solutions of nonlinear evolution equations. Modified equal-width, Burger Huxley and nonlinear heat conduction equations are chosen to illustrate the effectiveness of the method. The method is straightforward and concise, and its applications are promising. The exp- function method presents a wider applicability for handling nonlinear wave equations.
