Abstract:

This article mainly studies the well posedness of the Cauchy problem of a weakly dissipative Camassa-Holm equation in Sobolev-Gevrey spaces. Firstly, we demonstrate the local Gevrey regularity and analyticity of this equation. Then, we discuss the continuity of the data-to-solution map. Finally, we obtain the global Gevrey regularity of this system in Gevrey class $G_{\sigma}$ with $\sigma\geq 1$ in time.

Key words: A weakly dissipative Camassa-Holm equation, Analyticity, Gevrey class, Global Gevrey regularity
