abstract = {
The convergence of a two-scale FEM for elliptic problems in
divergence form with coefficients and geometries oscillating at
length scale ε << 1 is analyzed.
Full elliptic regularity independent of ε is shown
when the solution is viewed as mapping from the slow into the fast scale.
Two-scale FE spaces which are able to resolve the ε scale of the
solution with work independent of ε and without
analytical homogenization are introduced. Robust
in ε error estimates for the two-scale FE spaces
are proved. Numerical experiments confirm the
theoretical analysis.
