abstract
The present paper is devoted to study the asymptotic behavior of the solutions
of a Dirichlet nonlinear elliptic problem posed in a perforated domain O \ Kε,
where O ⊂ R
N
is a bounded open set and Kε ⊂ R
N
a closed set. Similarly to the
classical paper by D. Cioranescu and F. Murat, each set Kε is the union of disjoint
closed sets K
i
ε
, with critical size. But while there the sets K
i
ε
were balls periodically
distributed, here the main novelty is that the positions and the shapes of these sets
are random, with a distribution given by a preserving measure N -dynamical system
not necessarily ergodic. As in the classical result, the limit problem contains an extra
term of zero order, the “strange term” which depends on the capacity of the holes
relative to the nonlinear operator and also of its distribution. To prove these results
we introduce an original adaptation of the two scale convergence method combined
with the ergodic theory.

1. Introduction
Probably, the most well known result [15] in the homogenization of an elliptic problem with Dirichlet
conditions posed in a sequence of perforated domains is the following one: If O is a bounded open set of

is the union of closed balls (the holes) of critical size ε
