Stochastic homogenization of fractional obstacle problems

Francesco Deangelis, Matteo Focardi, Caterina Ida Zeppieri

We prove a stochastic homogenization result for a class of \emph{nonlinear} and \emph{nonlocal} variational problems in domains with many small randomly distributed (bilateral) obs…

Superlinear free-discontinuity models: relaxation and phase-field approximation

Sergio Conti, Matteo Focardi, Flaviana Iurlano

In this paper we develop the Direct Method in the Calculus of Variations for free-discontinuity energies whose bulk and surface densities exhibit superlinear growth, respectively f…

On the free boundary for thin obstacle problems with Sobolev variable coefficients

Giovanna Andreucci, Matteo Focardi, Emanuele Spadaro

We establish a quasi-monotonicity formula {for an intrinsic frequency function related to solutions to} thin obstacle problems with zero obstacle driven by quadratic energies with…

Approximation of functions with possibly infinite jump set

Sergio Conti, Matteo Focardi, Flaviana Iurlano

We prove an approximation result for functions such that is -integrable, , and is integrable over the jump set…

The regularity theory for the Mumford-Shah functional on the plane

Camillo De Lellis, Matteo Focardi

The aim of these notes is to give a complete self-contained account of the current state of the art in the regularity for planar minimizers and critical points of the Mumford-Shah…

Phase-field approximation of a vectorial, geometrically nonlinear cohesive fracture energy

Sergio Conti, Matteo Focardi, Flaviana Iurlano

We consider a family of vectorial models for cohesive fracture, which may incorporate -invariance. The deformation belongs to the space of generalized functions of…
