Luigi De Masi, Carlo Gasparetto
We generalize a result by Alberti, showing that, if a first-order linear differential operator belongs to a certain class, then any function is the absolutely c…

Regularity for free boundary surfaces minimizing degenerate area functionals
Carlo Gasparetto, Filippo Paiano, Bozhidar Velichkov
We establish an epsilon-regularity theorem at points in the free boundary of almost-minimizers of the energy $\mathrm{Per}_{w}(E)=\int_{\partial^*E}w\,\mathrm{d} {\mathscr{H}}^{n-1…
