Singular points of lightlike hypersurfaces of the de Sitter space

M.A. Akivis {\rm and} V.V. Goldberg

Department of Mathematics, New Jersey Institute of Technology, Newark NJ, USA

Abstract: We study singular points of lightlike hypersurfaces of the de Sitter space $S^{n+1}_1$ and the geometry of such hypersurfaces and use them for construction of an invariant normalization and an invariant affine connection of lightlike hypersurfaces.
