摘要

In this paper we partially classify isometric immersions from pseudo Riemannian space of constant sectional curvature into pseudo Riemannian space forms with flat space like normal bundle, if either the mean curvature vector field is parallel or if the manifolds are semi Euclidean spaces and the mean curvature vector field is of constant length. For hypersurfaces satisfying the above conditions we give a complete classification. (author). 11 refs. (Atomindex citation 27:046044)
