我们基于特征函数对称性约简构建了一个新的多分量 CKP 层次结构。它包含两种类型的CKP方程,它们具有自洽的来源,并给出了Lax表示。它还允许简化为 $k$ 约束的 CKP 层次结构和具有自洽源的 (1+1) 维孤子层次结构,其中包括两种类型的具有自洽源的 Kaup-Kuperschmidt 方程和具有自洽源的双向 Kaup-Kuperschmidt 方程。
We construct a new multi-component CKP hierarchy based on the eigenfunction symmetry reduction. It contains two types of CKP equation with self-consistent sources which Lax representations are presented. Also it admits reductions to $k$-constrained CKP hierarchy and to a (1+1)-dimensional soliton hierarchy with self-consistent source, which include two types of Kaup-Kuperschmidt equation with self-consistent sources and of bi-directional Kaup-Kuperschmidt equation with self-consistent sources.
