Backlund transformation, multiple wave solutions and lump solutions to a (3+1)-dimensional nonlinear evolution equation

摘要

In this paper, a (3+1)-dimensional nonlinear evolution equation is cast into Hirota bilinear form with a dependent variable transformation. A bilinear Backlund transformation is then presented, which consists of six bilinear equations and involves nine arbitrary parameters. With multiple exponential function method and symbolic computation, nonresonant-typed one-, two-, and three-wave solutions are obtained. Furthermore, two classes of lump solutions to the dimensionally reduced cases with y = x and y = z are both derived. Finally, some figures are given to reveal the propagation of multiple wave solutions and lump solutions.
