On New Hamiltonian Structures of Two Integrable Couplings

چکیده
In this paper, we present new Hamiltonian operators for the integrable couplings of Ablowitz–Kaup–Newell–Segur hierarchy and Kaup–Newell hierarchy. The corresponding Hamiltonians allow nontrivial degeneration. Multi-Hamiltonian structures are investigated. involutive property is proven known with respect to two Poisson brackets defined by operators.

Nonlinear bi-integrable couplings with Hamiltonian structures
Bi-integrable couplings of soliton equations are presented through introducing non-semisimple matrix Lie algebras on which there exist non-degenerate, symmetric and ad-invariant bilinear forms. The corresponding variational identity yields Hamiltonian structures of the resulting bi-integrable couplings. An application to the AKNS spectral problem gives bi-integrable couplings with Hamiltonian s...
متن کاملNonlinear continuous integrable Hamiltonian couplings
Based on a kind of special non-semisimple Lie algebras, a scheme is presented for constructing nonlinear continuous integrable couplings. Variational identities over the corresponding loop algebras are used to furnish Hamiltonian structures for the resulting continuous integrable couplings. The application of the scheme is illustrated by an example of nonlinear continuous integrable Hamiltonian...
متن کاملIntegrable Couplings, Variational Identities and Hamiltonian Formulations
We discuss Hamiltonian formulations for integrable couplings, particularly biand tri-integrable couplings, based on zero curvature equations. The basic tools are the variational identities over non-semisimple Lie algebras consisting of block matrices. Illustrative examples include dark equations and biand tri-integrable couplings of the KdV equation and the AKNS equations, generated from the en...
متن کاملConstructing nonlinear discrete integrable Hamiltonian couplings
Beginning with Lax pairs from special non-semisimple matrix Lie algebras, we establish a scheme for constructing nonlinear discrete integrable couplings. Discrete variational identities over the associated loop algebras are used to build Hamiltonian structures for the resulting integrable couplings. We illustrate the application of the scheme by means of an enlargedVolterra spectral problemandp...
متن کاملPre-hamiltonian Structures for Integrable Nonlinear Systems
Pre-Hamiltonian matrix operators in total derivatives are considered; they are defined by the property that their images are subalgebras of the Lie algebra of evolutionary vector fields. This construction is close to the Lie algebroids over infinite jet spaces. We assign a class of these operators and the brackets induced in their pre-images to integrable KdV-type hierarchies of symmetry flows ...
