Rotationally invariant hypersurfaces with constant mean curvature in the Heisenberg group H^n
Manuel Ritoré, César Rosales
In this paper we study sets in the -dimensional Heisenberg group $\hhn$ which are critical points, under a volume constraint, of the sub-Riemannian perimeter associated to the d…

Some isoperimetric comparison theorems for convex bodies in Riemannian manifolds
Vincent Bayle, César Rosales
We prove that the isoperimetric profile of a convex domain with compact closure in a Riemannian manifold satisfies a second order differential inequality which on…

Existence and characterization of regions minimizing perimeter under a volume constraint inside Euclidean cones
Manuel Ritoré, César Rosales
We study the problem of existence of regions separating a given amount of volume with the least possible perimeter inside a Euclidean cone. Our main result shows that nonexistence…
