Smoothness of Lipschitz minimal intrinsic graphs in Heisenberg groups
Luca Capogna, Giovanna Citti, Maria Manfredini
We prove that Lipschitz intrinsic graphs in the Heisenberg groups , with , which are vanishing viscosity solutions of the minimal surface equation are smooth.

Regularity of non-characteristic minimal graphs in the Heisenberg group
Luca Capogna, Giovanna Citti, Maria Manfredini
Minimal surfaces in the sub-Riemannian Heisenberg group can be constructed by means of a Riemannian approximation scheme, as limit of Riemannian minimal surfaces. We study the regu…
