We consider a Plateau problem in codimension 1 in the non-parametric setting. A Dirichlet boundary datum is given only on part of the boundary ∂Ω of a bounded convex domain Ω ⊂ R. Where the Dirichlet datum is not prescribed, we allow a free contact with the horizontal plane. We show existence of a solution, and prove regularity for the corresponding minimal surface. Finally we compare these solutions with the classical minimal surfaces of Meeks and Yau, and show that they are equivalent when… 

The relaxed area of $S^1$-valued singular maps in the strict $BV$-convergence

Given a bounded open set $\Omega \subset \mathbb R^2$, we study the relaxation   of the nonparametric area functional in the strict topology in $BV(\Omega;\mathbb R^2)$, and compute it for

New lower semicontinuity results for polyconvex integrals

SummaryWe study integral functionals of the formF(u, Ω)=∫Ωf(▽u)dx, defined foru ∈ C1(Ω;Rk), Ω⊑Rn. The functionf is assumed to be polyconvex and to satisfy the inequalityf(A) ≥c0¦ℳ(A)¦ for a suitable

We consider the relaxed area functional for vector valued maps and its exact value on the triple junction function u : B1(O) → R, a specific function which represents the first example of map whose

The $L^1$-relaxed area of the graph of the vortex map

We compute the value of the $L^1$-relaxed area of the graph of the map $u : B_l(0)\subset \mathbb R^2 \mapsto \mathbb R^2$, $u(x):= x/\vert x\vert$, $x \neq 0$, for all values of $l>0$.
