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.
