Anisotropic estimates of subelliptic type
Annamaria Montanari, Daniele Morbidelli
We discuss some estimates of subelliptic type related with vector fields satisfying the Hörmander condition. Our approach makes use of a class of approximate exponentials maps. Suc…

Multiexponential maps in Carnot groups with applications to convexity and differentiability
Annamaria Montanari, Daniele Morbidelli
We analyze some properties of a class of multiexponential maps appearing naturally in the geometric analysis of Carnot groups. We will see that such maps can be useful in at least…
