摘要：

In this paper, we give a construction of u(0) is an element of B-p,infinity(sigma) such that the corresponding solution to the Camassa-Holm equation starting from u(0) is discontinuous at t = 0 in the metric of B-p,infinity(sigma), which implies the ill-posedness for this equation in B-p,infinity(sigma). We also apply our method to the b-equation and Novikov equation. (C) 2021 Published by Elsevier Inc.
