A Difference Hamiltonian Operator and a Hierarchy of Generalized Toda Lattice Equations
A difference Hamiltonian operator with three arbitrary constants is presented. When the arbitrary constants in the Hamiltonian operator are suitably chosen, a pair of Hamiltonian operators are given.
On a class of coupled Hamiltonian operators and their integrable hierarchies with two potentials
We discuss at first in this paper the Gauge equivalence among several u‐linear Hamiltonian operators and present explicitly the associated Gauge transformation of Bäcklund type among them. We then
A bi-Hamiltonian formulation for triangular systems by perturbations
A bi-Hamiltonian formulation is proposed for triangular systems resulting from perturbations around solutions, from which infinitely many symmetries and conserved functionals of triangular systems
TWO SUPER-INTEGRABLE SYSTEMS AND ASSOCIATED SUPER-HAMILTONIAN STRUCTURES
The super extensions of g-cKdV and mKdV integrable systems are proposed. Two hierarchies of super-integrable nonlinear evolution equations are found. In addition, making use of the super-trace
Component-trace identities for Hamiltonian structures
We show that on a particular class of semi-direct sums of matrix Lie algebras, component traces of the matrix product can produce bilinear forms which are non-degenerate, symmetric and invariant
A HIERARCHY OF SOLITON EQUATIONS ASSOCIATED WITH A HIGHER-DIMENSIONAL LOOP ALGEBRA AND ITS TRI-HAMILTONIAN STRUCTURE
A new higher-dimensional loop algebra is given for which a Lax isospectral problem is set up whose compatibility condition gives rise to a Liouville integrable soliton hierarchy along with

A CLASS OF COUPLED KDV SYSTEMS AND THEIR BI-HAMILTONIAN FORMULATION
A Hamiltonian pair is proposed and thus a type of hereditary operators results. All the corresponding systems of evolution equations possess local bi-Hamiltonian formulation and a special choice of
Extending the Hamiltonian structures and new integrable systems
By starting with the known Hamiltonian structure of integrable systems, it is shown how extended Hamiltonian operators can be constructed using the conditions deduced by Dorfman for an operator to be
Extension of hereditary symmetry operators
Two models of candidates for hereditary symmetry operators are proposed and thus many nonlinear systems of evolution equations possessing infinitely many commuting symmetries may be generated. Some
Integrable coupled KdV systems
We give the conditions for a system of N-coupled Korteweg de Vries (KdV) type of equations to be integrable. We find the recursion operators of each subclass and give all examples for N=2.
On the structure of symplectic operators and hereditary symmetries
In the last fifteen years, there has been a remarlmble development in the exact analysis of certain nonlinear evolution equations, like tbe Korteweg-de Vries equation. I t is weH known that among the
