Asymptotic analysis of higher-order perturbations of the Perona--Malik functional

Andrea Braides, Irene Fonseca

The Gamma-limit of higher-order singular perturbations of the Perona-Malik functional is analyzed. The energies considered combine the critically scaled logarithmic term with a k-t…

$Γ$ -convergence and stochastic homogenization for functionals in the $A$ -free setting

Gianni Dal Maso, Rita Ferreira, Irene Fonseca

We obtain a compactness result for $Γ$ -convergence of integral functionals defined on $A$ -free vector fields. This is used to study homogenization problems for these func…
