Periodic unfolding and Robin problems in perforated domains
Doina Cioranescu, Patrizia Donato, Rachad Zaki · Comptes Rendus Mathématique · 2006
The periodic unfolding method was introduced in 2002 by D. Cioranescu et al. for the study of classical periodic homogenization. In this Note, we extend this method to perforated domains introducing also a boundary unfolding operator. As an application, we study the homogenization of some elliptic problems with Robin condition on the boundary of the holes.
