Compactness of $□_{b}$ in a CR manifold

Tran Vu Khanh, Stefano Pinton, Giuseppe Zampieri

This note is aimed at simplifying current literature about compactness estimates for the Kohn-Laplacian on CR manifolds. The approach consists in a tangential basic estimate in the…

Propagation of CR extendibility at the vertex of a complex sector

Luca Baracco, Stefano Pinton

We study propagation of CR extendibility at the vertex $p$ of an analytic sector $A$ contained in a CR manifold $M$ . Let $k$ be the weighted vanishing order of $M$ and $α$ the comp…

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.
