摘要

用Hirota双线性方法给出了（2+1）维Sawada-Kotera方程的N孤子解，然后用共轭参数法和长波极限法得到了通气解和块解，以及它们之间弹性碰撞性质的相互作用解。此外，根据块状孤子解和条纹孤子解的表达式，利用模拟方法直接研究了两个孤子在相互作用过程中的完全非弹性碰撞、反弹、吸收、分裂等粒子特性，揭示了这一现象背后反映的物理规律。

Interaction Solutions of the (2+1)-Dimensional Sawada-Kotera Equation

The N-soliton solution of the (2+1)-dimensional Sawada-Kotera equation is given by using the Hirota bilinear method, and then, the conjugate parameter method and the long-wave limit method are used to get the breather solution and the lump solution, as well as the interaction solution of the elastic collision properties between them. In addition, according to the expression of the lump-type soliton solution and the striped soliton solution, the completely inelastic collision, rebound, absorption, splitting, and other particle characteristics of the two solitons in the interaction process are directly studied with the simulation method, which reveals the laws of physics reflected behind the phenomenon.
