Application of (G'/G)-Expansion Method to Nonlinear Variants of the (2+1)-Dimensional Camassa-Holm-KP Equation

An analytic study of two nonlinear variants of the (2+1)-dimensional Camassa-Holm-KP equation is presented in this paper. The (G'/G)-expansion method is employed to obtain exact travelling wave solutions of the equations. The solutions gained from the proposed method have been verified with those obtained by the sine-cosine method and the tanh method. More importantly, other new and more general solutions are, likewise, found for these equations which are of great practical importance in physical and engineering problems.
