Compactness与达西定律的大尺度正则性

Compactness and Large-Scale Regularity for Darcy's Law

Zhongwei Shen

摘要:

本文研究了周期穿孔区域上具有Dirichlet条件的定常斯托克斯方程的定量均匀化问题。利用紧性方法,我们建立了速度的大尺度内点$C^{1, α}$和Lipschitz估计以及相应的压力估计。当这些估计与斯托克斯方程的经典正则性估计相结合时,得到一致Lipschitz估计。作为结果,我们也得到了$1<p<\infty$的一致$W^{k, p}$估计。

英文摘要:

This paper is concerned with the quantitative homogenization of the steady Stokes equations with the Dirichlet condition in a periodically perforated domain. Using a compactness method, we establish the large-scale interior $C^{1, α}$ and Lipschitz estimates for the velocity as well as the corresponding estimates for the pressure. These estimates, when combined with the classical regularity estimates for the Stokes equations, yield the uniform Lipschitz estimates. As a consequence, we also obtain the uniform $W^{k, p}$ estimates for $1<p<\infty$.
