Currents in Heisenberg groups
Bruno Franchi, Pierre Pansu
There are three approaches to currents tuned to the anisotropic geometry of Heisenberg groups: Ambrosio and Kirchheim's approach valid for general metric spaces; distributions dual…
Primitives of volume forms in Carnot groups
Annalisa Baldi, Bruno Franchi, Pierre Pansu
In the Euclidean space it is known that a function of a ball, with vanishing average,is the divergence of a vector field with$$\| F\|\_{ L^2(B)} \le C \|f\|\_…
Continuous primitives for higher degree differential forms in Euclidean spaces, Heisenberg groups and applications
Annalisa Baldi, Bruno Franchi, Pierre Pansu
It is shown that higher degree exact differential forms on compact Riemannian -manifolds possess continuous primitives whose uniform norm is controlled by their norm. A co…
-convergence of variational functionals with boundary terms in Stein manifolds
Eleonora Cinti, Bruno Franchi, María del Mar González
Let be an open subset of a Stein manifold and let be its boundary. It is well known that inherits a natural contact structure. In this paper we consider a family of…
