New solitary wave structures to the(3+1)dimensional Kadomtsev-Petviashvili and Schrödinger equation

The studies of the dynamic behaviors of nonlinear models arising in ocean engineering play a significant role in our daily activities.In this paper,an efficient mathematical technique,namely;the sine-Gordon expansion method is employed to construct the traveling wave solutions to the(3+1)-dimensional Kadomtsev-Petviashvili and(3+1)-dimensional nonlinear Schrödinger equations.Using suitable values of the parameters,the two-and three-dimensional figures of the obtained solutions are plotted.
