摘要
In this paper, we consider the long time dynamics of the solutions of the derivative nonlinear Schr & ouml;dinger equation on one dimensional torus without external parameters. By using rational normal form, we prove the long time stability for generic small initial data. (c) 2024 Elsevier Inc. All rights reserved.
