Variational approximation of size-mass energies for k-dimensional currents

Antonin Chambolle, Luca Alberto Davide Ferrari, Benoît Merlet

In this paper we produce a $$\Gamma$$-convergence result for a class of energies $Fk$ε$,a$ modeled on the Ambrosio-Tortorelli functional. For the choice k = 1 we show that $F1$ε$,a…
