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

Gianni Dal Maso, Rita Ferreira, Irene Fonseca

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

Monotonicity of the jump set and jump amplitudes in one-dimensional TV denoising

Riccardo Cristoferi, Rita Ferreira, Irene Fonseca +1

We revisit the classical problem of denoising a one-dimensional scalar-valued function by minimizing the sum of an $L^{2}$ fidelity term and the total variation, scaled by a regulari…

Junction in a thin multi-domain for nonsimple grade two materials in BH

We consider a thin multi-domain of $R^{N}$ , with $N \geq 2$ , consisting of a vertical rod upon a horizontal disk. In this thin multi-domain, we introduce a bulk energy density…
