Ting Zhang, Daoyuan Fang

摘要:

本文考虑三维不可压各向异性Navier-斯托克斯方程(\textit{ANS})的整体适定问题.为此,我们首先引入了标度不变的Besov-Sobolev型空间$B^{-1+\frac{2}{p},{1/2}}_{p}$和$B^{-1+\frac{2}{p},{1/2}}_{p}(T)$,$p\geq2$ .然后,我们证明了(\textit{ANS})的整体适定性,提供的初始数据是足够小的水平粘度相比,在某些适当的意义下,这是强于$B^{-1+\frac{2}{p},{1/2}}_{p}$规范。特别是,我们的结果意味着全球适定性(\textit{ANS})与高振荡的初始数据。

英文摘要:

In this paper, we consider a global wellposed problem for the 3-D incompressible anisotropic Navier-Stokes equations (\textit{ANS}). In order to do so, we first introduce the scaling invariant Besov-Sobolev type spaces, $B^{-1+\frac{2}{p},{1/2}}_{p}$ and $B^{-1+\frac{2}{p},{1/2}}_{p}(T)$, $p\geq2$. Then, we prove the global wellposedness for (\textit{ANS}) provided the initial data are sufficient small compared to the horizontal viscosity in some suitable sense, which is stronger than $B^{-1+\frac{2}{p},{1/2}}_{p}$ norm. In particular, our results imply the global wellposedness of (\textit{ANS}) with high oscillatory initial data.
