摘 要:
This paper studies the motion orbit of the solutions to (2+1)-dimensional Saw.–Kot.–Kad.–Pet. (SK–KP).We obtain orbit equation of a single lump before and after collision with line, lump, and breather waves by approximating solutions of SK-KP equation along some parallel orbits at infinity. We derive the mathematical expression of the phase change before and after the collision of a lump wave. At the same time, we give some collision plots to reveal the obvious phase change. Our method proposed to find the orbit equation of a lump wave can be applied to other integrable equations. The results expand the understanding of lump,breather, and hybrid solutions in soliton theory.
