  Discrete Periodic Homogenization for Linear Elasticity and Stokes Flow
Nicolas Neuss (Univ. Heidelberg)

We consider elliptic problems on domains with small-scale periodic or quasi-periodic heterogeneities. A discrete homogenization step in the spirit of [Neuss, Jaeger, Wittum 2001] is used for constructing a multigrid coarse-grid correction. Convergence of the resulting algorithm is shown both theoretically and practically.
