摘　　要：本文研究了(2 + 1)维Sawada-Kotera方程的转换动力学特性。通过Hirato双线性方法和复数化参数,我们给出孤立波解和一阶呼吸波解。基于转换条件,我们得到了几种转换波,包括(振荡) W型或M型孤子、和多峰孤子。接着,我们研究了转换波的时变性质。Under investigation in this work is the (2 + 1)-dimensional Sawada-Kotera equation. By the Hirato bilinear method and complex parameters, we give the solitary-wave solution and the first-order breath-wave solution. Based on the transition condition, we obtained the transformed waves, including the (oscillating) M- and W-shaped solitons and multi-peak solitons. Next, we investigate the time-varying features.
