Polarised Lie groups contactomorphic to stratified groups
Sebastiano Nicolussi, Alessandro Ottazzi
For a stratified group , we construct a class of polarised Lie groups, which we call modifications of , that are locally contactomorphic to it. Vice versa, we show that if a…

Conformal and CR mappings on Carnot groups
Michael G. Cowling, Ji Li, Alessandro Ottazzi +1
We consider a class of stratified groups with a CR structure and a compatible control distance. For these Lie groups we show that the space of conformal maps coincide with the spac…
