Math. Phys. 44:4756--4767 (2003)], are transformed into previously known integrable systems: one--into a pair of decoupled KdV equations, the other one--into a pair of coupled mKdV equations from a bi-Hamiltonian hierarchy of Kupershmidt.7 pagesExactly Solvable and Integrable SystemsMathematical PhysicsAnalysis of PDEstext
