Abstract
We introduce a novel solution concept, denotedα-dissipative solutions, that provides a continuousinterpolation between conservative and dissipative solutions of the Cauchy problem for the two-component Camassa–Holm system on the line with vanishing asymptotics. All theα-dissipativesolutions are global weak solutions of the same equation in Eulerian coordinates, yet they exhibitrather distinct behavior at wave breaking. The solutions are constructed after a transformation intoLagrangian variables, where the solution is carefully modified at wave breaking
