Query: Homogenization of Stokes equations in perforated domains: a unified
  approach   We consider the homogenization of the Stokes equations in a domain perforated
with a large number of small holes which are periodically distributed. In
[1,2], Allaire gave a systematic study on this problem. In this paper, we
introduce a unified proof for different sizes of holes for the homogenization
of the Stokes equations by employing a generalized cell problem inspired by
Tartar [17].
