关于Navier-斯托克斯方程的Kato方法

On Kato's method for Navier--Stokes Equations

Bernhard H. Haak, Peer-Christian Kunstmann

摘要:

本文研究了抽象形式下具有二次非线性项的抛物型方程的Kato方法。我们从线性系理论中提取了几个已知的性质,这些性质被证明是该方法的基本成分。我们给出了这些条件的充要条件,并提供了新的和更一般的证明,基于实插值。在Navier-斯托克斯方程的应用中,我们的方法统一了文献中已知的几个结果,部分是用不同的证明。此外,我们建立了新的存在性和唯一性的粗糙初始数据在任意区域的${\mathbb R}^3$和不规则区域的${\mathbb R}^n$。

英文摘要:

We investigate Kato's method for parabolic equations with a quadratic non-linearity in an abstract form. We extract several properties known from linear systems theory which turn out to be the essential ingredients for the method. We give necessary and sufficient conditions for these conditions and provide new and more general proofs, based on real interpolation. In application to the Navier-Stokes equations, our approach unifies several results known in the literature, partly with different proofs. Moreover, we establish new existence and uniqueness results for rough initial data on arbitrary domains in ${\mathbb R}^3$ and irregular domains in ${\mathbb R}^n$.
