Abstract

The nonlinearization method is extended to the investigation of coupled nonlinear Schrödinger equations associated with a 3×3 matrix eigenvalue problem, from which a new finite-dimensional Hamiltonian system is obtained by nonlinearization of the eigenvalue problem and its adjoint one. A scheme for generating involutive systems of conserved integrals is proposed, by which the finite-dimensional Hamiltonian system is further proved to be completely integrable in the Liouville sense. © 1999 Academic Press.
