Variational approach to the Hamiltonian structure of a new hierarchy of nonlinear equations
The authors determine the symplectic Hamiltonian structure of some nonlinear evolution equations obtained from two new isospectral problems, which were described some years ago by \textit{M. Jaulet} [C.N.R.S. Preprint-PM/82/1].
