Fifth order Camassa-Holm model with pseudo-peakons and multi-peakons

In this paper, we study a fifth order Camassa-Holm (FOCH) model with peakon solutions. Some interesting solutions are obtained including explicit single pseudo-peakons, two-peakon, and N-peakon solutions. In particular, detailed dynamical interactions for two-peakons and three-peakons are investigated numerically.
