Approximation of maximal Cheeger sets by projection
ESAIM: Modélisation mathématique et analyse numérique, Tome 43 (2009) no. 1, pp. 139-150.

This article deals with the numerical computation of the Cheeger constant and the approximation of the maximal Cheeger set of a given subset of ℝ d . This problem is motivated by landslide modelling as well as by the continuous maximal flow problem. Using the fact that the maximal Cheeger set can be approximated by solving a rather simple projection problem, we propose a numerical strategy to compute maximal Cheeger sets and Cheeger constants.
