Finite Difference Approximation of Free Discontinuity Problems

Functional Analysis 2007-05-23 v1

Abstract

We approximate functionals depending on the gradient of uu and on the behaviour of uu near the discontinuity points, by families of non-local functionals where the gradient is replaced by finite differences. We prove pointwise convergence, Γ\Gamma-convergence, and a compactness result which implies, in particular, the convergence of minima and minimizers.
