In quasi-periodic homogenization of elliptic equations or nonlinear
periodic homogenization of systems, the cell problem must be in
general set on the whole space. Numerically computing the
homogenization coefficient therefore implies a truncation error, due
to the fact that the problem is approximated on a bounded, large
domain. We present here an approach that improves the rate of
convergence of this approximation.
