Cross-kink multi-soliton solutions for the (3+1)-D Jimbo-Miwa equation

Abstract

Purpose – The purpose of this paper is to reveal the dynamical behavior of higher dimensional nonlinear wave by searching for the multi-wave solutions to the (3+1)-D Jimbo-Miwa equation. Design/methodology/approach – The authors apply bilinear form and extended homoclinic test approach to the (3+1)-D Jimbo-Miwa equation. Findings – In this paper, by using bilinear form and extended homoclinic test approach, the authors obtain new cross-kink multi-soliton solutions of the (3+1)-dimensional Jimbo-Miwa equation, including the periodic breathertype of kink three-soliton solutions, the cross-kink four-soliton solutions, the doubly periodic breather-type of soliton solutions and the doubly periodic breather-type of cross-kink two-soliton solutions. It is shown that the extended homoclinic test approach, with the help of symbolic computation, provides an effective and powerful mathematical tool for solving higher dimensional nonlinear evolution equations in mathematical physics. Research limitations/implications – The research manifests that the structures of the solution to higher dimensional nonlinear equations are diversified and complicated. Originality/value – The methods used in this paper can be widely applied to the research of spatial and temporal characteristics of nonlinear equations in physics and engineering technology. These methods are also conducive for people to know objective laws and grasp the essential features of the development of the world.
