On generalized ϕϕ-recurrent LP-Sasakian Manifolds

The object of the present paper was to introduce the notion of generalized  ϕϕ-recurrent LP-Sasakian manifold   and study its various geometric properties with the existence by an interesting example. Among others it is shown that a generalized ϕϕ-recurrent LP-Sasakian manifold is an Einstein manifold. Also it is proved that there exists no generalized projectively ϕϕ-recurrent LP-Sasakian manifold.
