Hypoellipticity and loss of derivatives with Appendix Analyticity and loss of derivatives
Joseph J. Kohn, Makhlouf Derridj, David S. Tartakoff
For each value of k, two complex vector fields satisfying the bracket condition are exhibited the sum of whose squares is hypoelliptic but not subelliptic - in fact the operator lo…

The \bar\partial_b Equation on Weakly Pseudoconvex CR Manifolds of Dimension 3
Joseph J. Kohn, Andreea Nicoara
Let M be a smooth, compact, orientable, weakly pseudoconvex manifold of dimension 3, embedded in C^N (N greater than or equal to 2), of codimension one or more in C^N, and endowed…

Superlogarithmic estimates on pseudoconvex domains and CR manifolds
J. J. Kohn
This paper is concerned with proving superlogarithmic estimates for the operator on pseudoconvex CR manifolds and using them to establish hypoellipticity of and o…
