Thema: | Two-scale regularity and sparse grids for homogenization problems |
We present a two-scale regularity theory for elliptic
homogenization problems in d-dimensional domains D (d=1,2,3) with
coefficients oscillating at period epsilon<
We design a FEM on sparse grids in 2d-dimensions and establish
robust in epsilon convergence rates for it.
The complexity of the FEM is shown to equal, up to log(N),
that of standard FEM in the physical d-dimensional domain on meshes
of
width epsilon | |
