Uniqueness of dissipative solutions for the Camassa-Holm equation

Analysis of PDEs 2024-08-28 v2

Abstract

We show that the Cauchy problem for the Camassa-Holm equation has a unique, global, weak, and dissipative solution for any initial data u0H1(R)u_0\in H^1(\mathbb{R}), such that u0,xu_{0,x} is bounded from above almost everywhere. In particular, we establish a one-to-one correspondence between the properties specific to the dissipative solutions and a solution operator associating to each initial data exactly one solution.
