On the Wave Structures to the (3+1)-Dimensional Boiti-Leon-Manna-Pempinelli Equation in Incompressible Fluid

In the present study, two effective methods, the Exp-function method and He's frequency formulation, are employed to investigate the dynamic behaviors of the (3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation, which is used widely to describe the incompressible fluid. A variety of the wave structures, including the dark wave, bright-dark wave and periodic wave solutions, are successfully constructed. Compared with the results attained by the methods, the obtained solutions are all new and have not been presented in the other literature. The diverse wave structures of the solutions are presented through numerical results in the form of three-dimensional plots and two-dimensional curves. It reveals that the proposed methods are powerful and straightforward, which are expected to be helpful for the study of travelling-wave theory in fluid.
