On whitham equations for camassa-holm
WebWe study the generalized Camassa-Holm equation which contains the Camassa-Holm (CH) equation and Novikov equation as special cases with the periodic boundary condition. We get a blow-up scenario and obtain the global existence of strong and weak solutions under suitable assumptions, respectively. Then, we construct the periodic peaked … WebThe Camassa–Holm equation has a number of constants of motion arising as eigenvalues of an associated spectral problem. ...
