Abstract
We construct and study Darboux transformations for the \((2{+}1)\)-dimensional Camassa–Holm system. We apply a reciprocal transformation that relates the \((2{+}1)\)-dimensional Camassa–Holm system and the linear system associated with the modified Kadomtsev–Petviashvili hierarchy. Using three Darboux transformation operators, we obtain three types of solutions for the \((2{+}1)\)-dimensional Camassa–Holm system, of which one is a multisoliton solution. In addition, we briefly discuss rational solutions.

使用Darboux变换获得(2 + 1)维Camassa-Holm系统的多孤子解
摘要
我们构造和研究\((2 {+} 1)\)维Camassa–Holm系统的Darboux变换。我们应用了倒数变换,该变换将\((2 {+} 1)\)-维Camassa–Holm系统和与修改后的Kadomtsev–Petviashvili层次结构关联的线性系统相关。使用三个Darboux变换算子,我们获得了\((2 {+} 1)\)维Camassa-Holm系统的三种类型的解决方案,其中一种是多孤子解决方案。此外,我们简要讨论了合理的解决方案。
