Parallel vector fields on the noninvariant hypersurface of a Sasakian manifold
Sachin Kumar Srivastava, Alok Kumar Srivastava, Dhruwa Narain
In 1970, Samuel I. Goldberg and Kentaro Yano defined the notion of noninvariant hypersurface of a Sasakian manifold [1]. In this paper we have studied the properties of parallel ve…
