The Hamiltonian Structure of Two Integrable Expanding Models
Keywords:
Integrable coupling;Hamiltonian structure;quadratic-form identityAbstract
In this paper, an extended loop algebra is constructed from which an isospectral problem established. It follows that the integrable couplings of the Tu hierarchy and M-AKNS-KN hierarchy are obtained, and their Hamilton structures are presented by the quadratic-form identity. Moreover, we guarantee that the expanding model we obtained are also Liouville integrable.Downloads
