Unconditional uniqueness for the periodic Benjamin-Ono equation by normal form approach

Analysis of PDEs 2022-05-17 v2

Abstract

We show unconditional uniqueness of solutions to the Cauchy problem associated with the Benjamin-Ono equation under the periodic boundary condition with initial data given in HsH^s for s>1/6s>1/6. This improves the previous unconditional uniqueness result in H1/2H^{1/2} by Molinet and Pilod (2012). Our proof is based on a gauge transform and integration by parts in the time variable.
