Ill-posedness for a generalized Camassa-Holm equation with higher-order nonlinearity in the critical Besov space

Wei Deng, Min Li, Xing Wu +1

In this paper, we prove that the Cauchy problem for a generalized Camassa-Holm equation with higher-order nonlinearity is ill-posed in the critical Besov space $B_{\infty ,1}^1(\mathbb{R})$…
