,On a Model “Sum of Squares” Operator,We study the real analytic and Gevrey regularity of the solutions to a type of “sum of squares” model operator, see (1), in two variables and obtain a result in agreement with Treves conjecture.

Equality of Commutator Type and Levi Form Type for an ,-Dimensional Bundle,Let . be a smooth real hypersurface in ., and let . be an (.) dimensional subbundle of the CR tangent bundle of .. We prove that the commutator type and the Levi form type associated with . are equal to each other. This answers affirmatively the generalized D’Angelo Conjecture for an (.) dimensional subbundle of the CR tangent bundle.

The image of the Borel map is a subalgebra of the ring of formal power series .: However, the general structure of the image is not yet well understood. In all examples studied so far, the image is given by the tensor product of a ring of formal series with a ring of convergent series.

Star Actors in the Hollywood Renaissance hypersurfaces in complex manifolds and provide some new insight into the CR geometry of such hypersurfaces. Then we establish some new results for the two notions of flatness. Among other things, we prove there exists a family ., parameterized by the real numbers (and, hence, is uncountably infinit
