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…

A Hadamard-type open map theorem for submersions and applications to completeness results in Control Theory
Andrea Bonfiglioli, Annamaria Montanari, Daniele Morbidelli
We prove a quantitative openness theorem for submersions under suitable assumptions on the differential. We then apply our result to a class of exponential maps appearing in…

Pseudohermitian invariants and classification of CR mappings in generalized ellipsoids
Roberto Monti, Daniele Morbidelli
We discuss the problem of classifying all local CR diffeomorphisms of a strictly pseudoconvex surface. Our method exploits the Tanaka--Webster pseudohermitian invariants, their tra…
