In this paper we show the following property of a non Levi flat real hypersurface in C^{n+1} : if the unit characteristic direction T is a geodesic, then it is an eigenvector of the second fundamental form and the relative eigenvalue is constant. As an application we prove a symmetry result of Alexandrov type for compact hypersurfaces in C^{n+1} with positive constant Levi mean curvature.

Abstract

In this paper we show the following property of a non Levi flat real hypersurface in C^{n+1} : if the unit characteristic direction T is a geodesic, then it is an eigenvector of the second fundamental form and the relative eigenvalue is constant. As an application we prove a symmetry result of Alexandrov type for compact hypersurfaces in C^{n+1} with positive constant Levi mean curvature.
