Minimality of free-boundary axial hyperplanes in high dimensional circular cones via calibration

Giacomo Vianello

Consider an $(n + 1)$ -dimensional circular cone with opening angle $α \in (0, π)$ . Using a free-boundary adaptation of the classical calibration method, we prove that, for $n \geq 4$ ,…

Plateau's Problem for intrinsic graphs in the Heisenberg Group

Roberto Monti, Giacomo Vianello

Using a geometric construction, we solve Plateau's Problem in the Heisenberg group $H^{1}$ for intrinsic graphs defined on a convex domain $D$ , under a smallness condition…

Stability of axial free-boundary hyperplanes in circular cones

Gian Paolo Leonardi, Giacomo Vianello

Given an axially-symmetric, $(n + 1)$ -dimensional convex cone $Ω \subset R^{n + 1}$ , we study the stability of the free-boundary minimal surface $Σ$ obtained by intersecting $Ω…

Free-Boundary Monotonicity for Almost-Minimizers of the Relative Perimeter

Gian Paolo Leonardi, Giacomo Vianello

Let $E \subset Ω$ be a local almost-minimizer of the relative perimeter in the open set $Ω \subset R^{n}$ . We prove a free-boundary monotonicity inequality for $E$ at a poi…
