Global hypoellipticity of the Kohn-Laplacian $□_{b}$ on pseudoconvex CR manifolds

Tran Vu Khanh

Let $X$ be a complex manifold and $M \subset X$ a compact, smooth, pseudoconvex CR manifold of dimension $2 n - 1$ . (Here $n \geq 3$ or, in case $n = 2$ , it is made the extra assumption th…

Loss of derivatives in the infinite type

T. V. Khanh, S. Pinton, G. Zampieri

We discuss loss of derivatives for degenerate vector fields obtained from infinite type exponentially non-degenerate hypersurfaces of $\C^2$.

Loss of derivatives for systems of complex vector fields and sums of squares

Tran Vu Khanh, Stefano Pinton, Giuseppe Zampieri

We discuss, both for systems of complex vector fields and for sums of squares, the phenomenon discovered by Kohn of hypoellipticity with loss of derivatives.

Hypoellipticity of the $\partial ˉ$ -Neumann problem at exponentially degenerate points

Tran Vu Khanh, Giuseppe Zampieri

We prove that the $\partial ˉ$ -Neumann solution operator is locally regular in a domain which has compactness estimates, is of finite type outside a curve transversal to the CR d…
