Abstract

Let $(M^{2n},g)$ be a real hypersurface with recurrent shape
operator and tangent to the structure vector field $xi$ of the Sasakian space form
$widetilde{M}(c)$. We show that if the shape operator $A$ of $M$ is
recurrent then it is parallel. Moreover, we show that $M$
is locally a product of two constant $phi-$sectional curvature
spaces.
