Covariant almost analytic vector field on Q - Quasi umbilical hypersurface of a Sasakian manifold

In this paper we have studied the properties of covariant almost analytic vector field on Q - quasi umbilical hypersurface $M$ of a Sasakian manifold $\tilde{M}$ with $(\varphi ,g,u,v,\lambda )-$structure and obtained the scalars $\alpha$ and $\beta$ using $1-formu,v$ covariant almost analytic for the hypersurface $M$ to be totally umbilical and cylindrical.
