Computation of conserved densities for systems of nonlinear differential-difference equations
A new method for the computation of conserved densities of nonlinear differential-difference equations is applied to Toda lattices and discretizations of the Korteweg-de Vries and nonlinear Schrodinger equations.

| Zusammenfassung: | A new method for the computation of conserved densities of nonlinear
differential-difference equations is applied to Toda lattices and
discretizations of the Korteweg-de Vries and nonlinear Schrodinger equations.
The algorithm, which can be implemented in computer algebra languages such as
Mathematica, can be used as an indicator of integrability. |
