Quasi-crystalline phase separation in one dimension
Riccardo Cristoferi, Lorenza D'Elia
We investigate a Modica-Mortola energy in heterogeneous materials with a quasi-crystalline microstructure, described by a suitable notion of almost periodicity. In the regime where…
Relaxation of variational problems in the space of functions with bounded -variation: interaction with measures and lack of concentration phenomena
Lorenza D'Elia, Elvira Zappale
We prove an integral representation result for variational functionals in the space of functions with bounded -variation where denotes…
First-order homogenization
Riccardo Cristoferi, Lorenza D'Elia
We provide a first-order homogenization result for quadratic functionals. In particular, we identify the scaling of the energy and the explicit form of the limiting functional in t…
Homogenization of supremal functionals in the vectorial case (via -approximation)
Lorenza D'Elia, Michela Eleuteri, Elvira Zappale
We propose a homogenized supremal functional rigorously derived via -approximation by functionals of the type $\underset{x\inΩ}{\mbox{ess-sup}}\hspace{0.03cm} f\left(\frac{x}{…
