报告摘要:
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 of Tartar, Cioranescu-Murat, Allaire in 80s and 90s. In this paper, we show that these classical homogenization results in a bounded domain can be extended to the whole space R^d. Our results cover all three cases corresponding to different sizes of holes and cover all d\geq 2.
