Abstract

This research project deals with a correspondence between Levi-flat CR structures and systems of real vector fields. In several different models, this correspondence allows to obtain results about vanishing of cohomology spaces, global solvability and global hypoellipticity of one of the structures from information about the other. In presence of a Lie group action, the naturally associated real models of such CR structures have been heavily studied recently.
