BV Minimizers of the area functional in the Heisenberg group under the bounded slope condition
Andrea Pinamonti, Francesco Serra Cassano, Giulia Treu +1
We consider the area functional for t-graphs in the sub-Riemannian Heisenberg group and study minimizers of the associated Dirichlet problem. We prove that, under a bounded slope c…
