Abstract

The two variables ( 𝐺 / 𝐺 , 1 / 𝐺 ) -expansion method is proposed in this paper to construct new exact traveling wave solutions with parameters of the nonlinear ( 3 + 1 ) -dimensional Kadomtsev-Petviashvili equation. This method can be considered as an extension of the basic ( 𝐺 / 𝐺 ) -expansion method obtained recently by Wang et al. When the parameters are replaced by special values, the well-known solitary wave solutions and the trigonometric periodic solutions of this equation were rediscovered from the traveling waves.
