Abstract

In this paper we refine the V-cycle multi-grid convergence proofs of Hackbusch and Wittum. We obtain a sharper bound for the contraction number. With this new bound we are able to prove robustness of the V-cycle applied to anisotropic equations when a suitable smoother is used. For a model problem we give some quantitative results.
