Local Conservation Laws and the Hamiltonian Formalism for the AblowitzâLadik Hierarchy
Local Conservation Laws and the Hamiltonian Formalism for the AblowitzâLadik Hierarchy
We derive a systematic and recursive approach to local conservation laws and the Hamiltonian formalism for the AblowitzâLadik (AL) hierarchy. Our methods rely on a recursive approach to the AL hierarchy using Laurent polynomials and on asymptotic expansions of the Green's function of the AL Lax operator, a fiveâdiagonal finite âŚ
