Global approximate controllability of the Camassa–Holm equation by a finite dimensional force

Year: 2025

Type: article

Abstract: In this article, we consider the Camassa–Holm equation posed on the periodic domain T. We show that in any positive time, the Camassa–Holm equation is globally approximately controllable in Hs(T) for s > 3/2 by a three dimensional external force. The proof is based on Agrachev–Sarychev approach in geometric control theory. In particular, our three dimensional control prevents a finite time blow up of the solution of Camassa–Holm equation in Hs(T) for s > 3/2.
