We consider higher-order Camassa–Holme quations describing exponential curves of the manifold of smooth orientation-preserving diffeomorphisms of the unit circle in the plane.

Abstract
We consider higher-order Camassa–Holme quations describing exponential curves of the manifold of smooth orientation-preserving diffeomorphisms of the unit circle in the plane. We establish the existence of global weak solutions. We also present some invariant spaces under the action of the equation. Moreover, we prove a “weak equals strong” uniqueness result.File in questo prodotto:
