Abstract

We consider a nonlinear Robin problem for the Poisson equation in an unbounded periodically perforated domain. The domain has a periodic structure, and the size of each cell is determined by a positive parameter delta. The relative size of each periodic perforation is instead determined by a positive parameter epsilon. We prove the existence of a family of solutions which depends on epsilon and delta and we analyze the behavior of such a family as (epsilon,delta) tends to (0,0 ) by an approach which is alternative to that of asymptotic expansions and of classical homogenization theory.
