Abstract In this paper, the Cauchy problem of an n-component Camassa–Holm system is considered. The local well-posedness in the critical Besov space ( B 2 , 1 3 2 ) n is established, and it is shown that the data-to-solution map is Holder continuous. We finally give two new blow-up conditions for the initial data to this system by virtue of the H 1 -norm conservation law.
