BV functions and sets of finite perimeter in sub-Riemannian manifolds
Luigi Ambrosio, Roberta Ghezzi, Valentino Magnani
We give a notion of BV function on an oriented manifold where a volume form and a family of lower semicontinuous quadratic forms are given. When we consi…

On Almost-Riemannian Surfaces
Roberta Ghezzi
An almost-Riemannian structure on a surface is a generalized Riemannian structure whose local orthonormal frames are given by Lie bracket generating pairs of vector fields that can…

Two-Dimensional Almost-Riemannian Structures with Tangency Points
Andrei Agrachev, Ugo Boscain, Grégoire Charlot +2
Two-dimensional almost-Riemannian structures are generalized Riemannian structures on surfaces for which a local orthonormal frame is given by a Lie bracket generating pair of vect…
