A new discrete two-by-two matrix spectral problem with two potentials is introduced, followed by a hierarchy of integrable lattice equations obtained through discrete zero curvature equations. It is shown that the Hamiltonian structures of the resulting integrable lattice equations are established b
A type of higher dimensional loop algebra is constructed from which an isospectral problem is established. It follows that an integrable coupling, actually an extended integrable model of the existed solitary hierarchy of equations, is obtained by taking use of the zero curvature equation, whose Ham
A new isospectral problem is designed by considering a subalgebra A 1 of loop algebra e A A 1 , which possesses two power gaps of spectral parameter k. It follows that a new type of integrable system is obtained by choosing suitable modified term and Tu-model, which has bi-Hamiltonian structure. Fur
