Abstract:

In this paper, we discussed the oriented closed pseudo-umbilical submanifold with parallel second fundamental form in a Riemannian manifold Nn+p. we prove a pinching theorem for length of second fundamental form for this submanifolds in Nn+p.

Key words: Parallelsecondfundamentalform, Pseudoumbilicalsubmanifolds, Totallygeodesic
