A sphericity criterion for strictly pseudoconvex hyper surfaces in $C^{2}$ via invariant curves

Florian Bertrand, Giuseppe Della Sala, Bernhard Lamel

We prove that if every chain on a strictly pseudoconvex hypersurface $M$ in $C^{2}$ coincides with the boundary of a stationary disc, then $M$ is locally spherical.

Levi equation and local maximum property

Giuseppe Della Sala, Giuseppe Tomassini

The aim of the paper is to study the level sets of the solutions of Dirichlet problems for the Levi operator on strongly pseudoconvex domains $I^c ◯$ in $C^{2}$ . Such solutions…
