Abstract

In this paper, we employ the tanh method for traveling wave solutions of coupled nonlinear Klein-Gordon equations. Based on the idea of the tanh method, a simple and efficient method is proposed for obtaining exact solutions of nonlinear evolution equations. The solutions obtained include solitons and periodic solutions.
