Hypoellipticity and Non Hypoellipticity for Sums of Squares of Complex Vector Fields
In this talk we give a report on a paper where we consider a model sum of squares of planar complex vector fields, being close to Kohn's operator but with a point singularity. The characteristic variety of the operator is the same symplectic real analytic manifold as Kohn's. We show that t...
