Real-analytic coordinates for smooth strictly pseudoconvex CR-structures

Complex Variables 2019-06-25 v1 Differential Geometry

Abstract

For a smooth strictly pseudoconvex hypersurface in a complex manifold, we give a necessary and sufficient condition for being CR-diffeomorphic to a real-analytic CR manifold. Our condition amounts to a holomorphic extension property for the canonically associated function expressing 22-jets of the formal Segre varieties in terms of their 11-jets. We also express this condition in equivalent terms for a Fefferman type determinant
