An integral formula on the Heisenberg group
Francescopaolo Montefalcone
Let Hn denote the (2n + 1)-dimensional (sub-Riemannian) Heisenberg group. In this note, we shall prove an integral identity (see Theorem 1.2) which generalizes a formula obtained i…

Geometric inequalities in Carnot groups
Francescopaolo Montefalcone
Let $\GG$ be a sub-Riemannian -step Carnot group of homogeneous dimension . In this paper, we shall prove several geometric inequalities concerning smooth hypersurfaces (i.e.…

Stable H-minimal hypersurfaces
Francescopaolo Montefalcone
We prove some stability results for smooth H-minimal hypersurfaces immersed in a sub-Riemannian k-step Carnot group G. The main tools are the formulas for the 1st and 2nd variation…
