Abstract:

We prove two new approximation results of H-perimeter minimizing boundaries by means of intrinsic Lipschitz functions in the setting of the Heisenberg group $H^n$ with $n\ge2$. The first one is an improvement of $[19]$ and is the natural reformulation in $H^n$ of the classical Lipschitz approximation in $R^n$. The second one is an adaptation of the approximation via maximal function developed by De Lellis and Spadaro $[11]$.
