无限深中的时间准周期重力水波

Time Quasi-Periodic Traveling Gravity Water Waves in Infinite Depth

Roberto Feola, Filippo Giuliani

摘要:

本文给出了关于无限深二维纯重力水波系统准周期行波存在性的最新结果[8]。给出了从完全共振椭圆不动点分支的拟周期水波解的第一个存在性结果。证明是基于Nash-Moser格式,Birkhoff标准形方法和伪微分学技术。我们处理的组合问题的小因子和完全非线性性质的方程。

英文摘要:

We present the recent result [8] concerning the existence of quasi-periodic in time traveling waves for the 2d pure gravity water waves system in infinite depth. We provide the first existence result of quasi-periodic water waves solutions bifurcating from a completely resonant elliptic fixed point. The proof is based on a Nash-Moser scheme, Birkhoff normal form methods and pseudo-differential calculus techniques. We deal with the combined problems of small divisors and the fully-nonlinear nature of the equations.
