The dynamical stability of the periodic peaked solitons for a generalized Camassa–Holm equation is studied in this paper. Its generalization version is known to admit a single-peaked soliton solutions, and is shown here to possess a periodic peakon soliton. Then by constructing a Lyapunov functionals, we derive that the periodic peakon solution is orbitally stable under small perturbations in the energy space .

广义 Camassa-Holm 方程的周期峰的轨道稳定性
本文研究了广义Camassa-Holm方程的周期性峰值孤子的动力学稳定性。众所周知,它的泛化版本承认单峰孤子解,并在此处显示为具有周期性峰孤子。然后通过构造一个 Lyapunov 泛函,我们推导出周期性 peakon 解在能量空间的小扰动下是轨道稳定的.
