A Note on the Convergence Analysis of a Diffuse-domain Approach

Sebastian Franz, Hans-Görg Roos, Roland Gärtner and Axel Voigt


We analyse the error behaviour of a diffuse-domain approximation of an elliptic differential equation. In one dimension and for a half-plane problem in two dimensions an approximation quality of order one in the interface parameter is shown. Some supporting numerical experiments are also presented.
