| Abstract: | In this paper, we discussed the oriented closed pseudo-u mbilical submanifold with parallel second fundamental form in a Riemannian manif old N n p . we prove a pinching theorem for length of second fundamental for m for this submanifolds in $N n p .$ |

| Keywords: | Parallel sec ond fundamental form Pseudo-umbilical submanifolds Totally geodesic. |
