On the non-integrability of Roy's system

Recently a coupled system of nonlinear evolution equations was introduced by P.K. Roy, together with a proposed bi-Hamiltonian structure and supersymmetric version. In this note we point out that in fact the system only appears to have one Hamiltonian structure, as well as applying Painleve analysis which indicates that the system is non-integrable. We also present travelling wave solutions to the system in terms of the Weierstrass zeta function, together with the degeneration to a solitary wave.
