Abstract

A null manifold is a differentiable manifold M endowed with a degenerate metric tensor g. In this work we provide sufficient conditions for a null manifold to be isometrically immersed as a hypersurface into a simple connected semi-Riemannian manifold of constant sectional curvature c and index q

Keywords

Degenerate metric, isometric immersion, Gauss-Codazzi-Ricci equations
