Abstract

We present a reciprocal transformation which links the Geng-Xue equation to a particular reduction of the first negative flow of the Boussinesq hierarchy. We discuss two reductions of the reciprocal transformation for the Degasperis-Procesi and Novikov equations, respectively. With the aid of the Darboux transformation and the reciprocal transformation, we obtain a compact parametric representation for the smooth soliton solutions such as multi-kink solutions of the Geng-Xue equation.

具有三次非线性的二分量峰值系统的光滑多孤子解

我们提出了一个倒易变换，它将耿雪方程与Boussinesq层次的第一个负流的一个特殊约简联系起来。我们分别讨论了Degasperis-Procesi和Novikov方程的倒数变换的两个约简。借助于Darboux变换和互易变换，我们得到了耿雪方程的光滑孤立子解（如多扭结解）的一个紧致参数表示。
