The sharp upper bounds for the first positive eigenvalue of the Kohn-Laplacian on compact strictly pseudoconvex hypersurfaces

Song-Ying Li, Guijuan Lin, Duong Ngoc Son

We give sharp and explicit upper bounds for the first positive eigenvalue $λ_{1} (□_{b})$ of the Kohn-Laplacian on compact strictly pseudoconvex hypersurfaces in $C^{n + 1}$ i…

A family of compact strictly pseudoconvex hypersurfaces in $C^{2}$ without umbilical points

Peter Ebenfelt, Duong Ngoc Son, Dmitri Zaitsev

We prove the following: For $ε > 0$ , let $D_{ε}$ be the bounded strictly pseudoconvex domain in $C^{2}$ given by \begin{equation*} (\log|z|)^2+(\log|w|)^2<ε^2. \end{equation*} Th…
