This paper deals with the non-uniform dependence and persistence properties for a coupled Camassa-Holm equations. Using the method of approximate solutions in conjunction with well-posedness estimate, it is proved that the solution map of the Cauchy problem for this coupled Camassa-Holm equation is not uniformly continuous in Sobolev spaces H-s with s>3/2. On the other hand, the persistence properties in weighted L-p spaces for the solution of this coupled Camassa-Holm system are considered. Copyright (c) 2016 John Wiley & Sons, Ltd.
