Abstract

The elliptic equations with strongly jumping anisotropic diffusion coefficients as well as equations defined in domains involving thin substructures face a wide range of applications in the problems of structural mechanics, porous media, magnetostatics and biology. Unstable convergence of the traditional iterative schemes appears to be a bottleneck in efficient numerical treatment of large scale computational problems with degeneration in coefficients and geometries.
