A Generalized Two-Component Camassa-Holm System with Complex Nonlinear Terms and Waltzing Peakons

Abstract

AbstractIn this paper, we deal with the Cauchy problem for a generalized two-component Camassa-Holm system with waltzing peakons and complex higher-order nonlinear terms. By the classical Friedrichs regularization method and the transport equation theory, the local well-posedness of solutions for the generalized coupled Camassa-Holm system in nonhomogeneous Besov spaces and the critical Besov space $$B^{5/2}_{2,1}\times B^{5/2}_{2,1}$$ B 2 , 1 5 / 2 × B 2 , 1 5 / 2 was obtained. Besides the propagation behaviors of compactly supported solutions, the global existence and precise blow-up mechanism for the strong solutions of this system are determined. In addition to wave breaking, the another one of the most essential property of this equation is the existence of waltzing peakons and multi-peaked solitray was also obtained.
