摘要

在本文中,我们利用频率分解技术直接证明了无边界二维黎曼流形上纳维-斯托克斯方程的全局存在性和正则性。我们的技术受到 Mattingly 和 Sinai $\href{https://doi.org/10.1142/S0219199799000183}{[15]}$ 方法的启发,该方法是在平面背景上周期性边界条件的背景下发展起来的,它基于傅里叶系数的最大原则。扩展到一般流形需要一些新思路,这些新思路与我们的设置中较不利的谱定位特性有关。我们的论证利用了频率投影算子、源自非线性施罗丁格方程研究的多线性估计以及微观局部分析的思想。

A geometric trapping approach to global regularity for 2D Navier–Stokes on manifolds
In this paper, we use frequency decomposition techniques to give a direct proof of global existence and regularity for the Navier–Stokes equations on two-dimensional Riemannian manifolds without boundary. Our techniques are inspired by an approach of Mattingly and Sinai $\href{https://doi.org/10.1142/S0219199799000183}{[15]}$ which was developed in the context of periodic boundary conditions on a flat background, and which is based on a maximum principle for Fourier coefficients. The extension to general manifolds requires several new ideas, connected to the less favorable spectral localization properties in our setting. Our arguments make use of frequency projection operators, multilinear estimates that originated in the study of the non-linear Schr¨odinger equation, and ideas from microlocal analysis.
