Higher-order boundary layers and regularity for Stokes systems over rough boundaries

Mitsuo Higaki, Jinping Zhuge

AI总结:

本文研究了周期振荡 John 域中 Stokes 系统的大尺度边界正则性,通过构造任意阶边界层校正子,推广了已有的一阶和二阶结果,并证明了任意阶的大尺度正则性估计及 Liouville 定理。

摘要:

本文研究周期振荡 John 域中 Stokes 系统的大尺度边界正则性。主要贡献是构造任意阶的边界层校正子。这是对仅限于一阶和二阶的已知结果的重要推广。作为应用,我们证明了 Stokes 系统任意阶的大尺度正则性估计及 Liouville 定理。结果亦关联粗糙边界上粘性流体的高阶边界层尾部与壁定律。

英文摘要:

In this paper, we study the large-scale boundary regularity for the Stokes system in periodically oscillating John domains. Our main contribution is the construction of boundary layer correctors of arbitrary order. This is a significant generalization of the known results restricted to the first and second orders. As an application, we prove the large-scale regularity estimate, as well as a Liouville theorem, of arbitrary order for the Stokes system. Our results are also related to higher-order boundary layer tails and wall laws in viscous fluids over rough boundaries.
