Abstract [en]

We use the bi-Hamiltonian structure of the Camassa-Holm equation to show that its conservation laws Hn[m] are homogeneous with respect to the scaling m → λm. Moreover, a direct argument is presented proving that H-1, H-2,..., are of local character. Finally, simple representations of the conservation laws in terms of their variational derivatives are derived and used to obtain a constructive scheme for computation of the Hns.
