Regularity Results for a free interface problem with Hölder coefficients
Luca Esposito, Lorenzo Lamberti
We study a class of variational problems involving both bulk and interface energies. The bulk energy is of Dirichlet type albeit of very general form allowing the dependence from t…

Variational analysis in one and two dimensions of a frustrated spin system: chirality transitions and magnetic anisotropic transitions
Andrea Kubin, Lorenzo Lamberti
We study the energy of a ferromagnetic/antiferromagnetic frustrated spin system with values on two disjoint circumferences of the 3-dimensional unit sphere in a one-dimensional and…
