Unconditional well-posedness for the Kawahara equation

[摘要] This article is concerned with the unconditional well-posedness for the Kawahara equation on the real line and shows that this holds true for initial data in L-2(R). This is achieved by applying an infinite iteration scheme of normal form reductions. (C) 2021 Elsevier Inc. All rights reserved.
