Abstract

We consider a two-component Hamiltonian system of partial

Popowicz, which has the form of a coupling between the Camassa-Holm and Degasperis-Procesi equations.

system itself is not integrable. Nevertheless, as one of the authors showed with Irle, it admits

peakons being determined by a Hamiltonian system on a phase space of dimension $3N$.

integrable. We present the explicit solution for the two-peakon dynamics, and describe

some of the novel features of the interaction of peakons in the Popowicz system.
