Abstract

We give a more elementary proof of a result by Ambrosio and Fusco and Hutchinson to estimate the Hausdorff dimension of the singular set of minimizers of the Mumford?Shah energy (see [Calc. Var. Partial Differential Equations 16 (2003) and no. 2 and 187?215 and Theorem 5.6]). On the one hand and we follow the strategy of the above mentioned paper; but on the other hand our analysis greatly simplifies the argument since it relies on the compactness result proved by the first two authors in [J. Math. Pures Appl. 100 (2013) and 391?409 and Theorem 13] for sequences of local minimizers with vanishing gradient energy and and the regularity theory of minimal Caccioppoli partitions and rather than on the corresponding results for Almgren's area minimizing sets.
