摘要
For Sobolev exponent s > 3/2, it is shown that the data-to-solution map for the 2-component Camassa-Holm system is continuous from H-s x Hs-1(T) into C([0, T]; H-s x Hs-1(T)) but not uniformly continuous. The proof of non-uniform dependence on the initial data is based on the method of approximate solutions, delicate commutator and multiplier estimates, and well-posedness results for the solution and its lifespan. Also, the solution map is Holder continuous if the H-s x Hs-1(T) norm is replaced by an H-r x Hr-1(T) norm for 0 <= r < s.
