The modified simple equation method is an efficient method for obtaining exact solutions of nonlinear evolution equations. In this paper, the modified simple equation method is applied to construct exact solutions of the modified equal width (MEW) equation and the Fisher equation and the nonlinear Telegraph equation and the Cahn–Allen equation. The Fisher… (More)
In this paper, we employ the infinite series method for travelling wave solutions of the coupled Klein-Gordon equations. Based on the idea of the infinite series method, a simple and efficient method is proposed for obtaining exact solutions of nonlinear evolution equations. The solutions obtained include solitons and periodic solutions.
