Scannell, Kevin P. Flat conformal structures and the classification of de Sitter manifolds. (English) Zbl 0941.53040 Commun. Anal. Geom. 7, No. 2, 325-345 (1999). The main result is the following Theorem. Every de Sitter spacetime which is a small regular neighborhood of a compact spacelike hypersurface isometrically embeds in a standard de Sitter spacetime.
