Poisson和斯托克斯方程在全空间的均匀化

Homogenization of Poisson and Stokes equations in the whole space

Yong Lu

摘要:

本文研究了周期性分布小孔的Poisson方程和斯托克斯方程的均匀化问题。有界区域中的周期均匀化是很好理解的,遵循[24,4,1,2]中的经典结果。在本文中,我们证明了这些经典的均匀化结果在一个有界区域可以推广到整个空间${\mathbb R}^d$。我们的结果涵盖了所有三种情况下,对应于不同大小的孔,并涵盖所有$d\geq 2$。

英文摘要:

We consider the homogenization of the Poisson and the Stokes equations in the whole space perforated with periodically distributed small holes. The periodic homogenization in bounded domains is well understood, following the classical results in [24, 4, 1, 2]. In this paper, we show that these classical homogenization results in a bounded domain can be extended to the whole space ${\mathbb R}^d$. Our results cover all three cases corresponding to different sizes of holes and cover all $d\geq 2$.
