In this paper we study, Projective and pseudo-Projective curvature tensors in Kenmotsu manifolds with respect to semi-symmetric connection. And obtained the results on ϕ -Projectvely and ϕ -pseudo-Projectvely flat Kenmotsu manifolds with semi-symmetric metric connection, [ABSTRACT FROM AUTHOR]

In this paper we study generalized ϕ-recurrent almost C(λ) manifolds. It is proved that a generalized ϕ-recurrent almost C(λ) manifold is an Einstein manifold. Wealso find some relations between the associated 1-forms. Also it is shown that generalized concircular, conformal ϕ-recurrent almost C(λ) Manifolds are Einsteins. Further it is proved that conservative concircular almost C(λ) manifold is an Einstein manifold and shown that the concircular curvature tensor is irrotational on almost C(λ) manifolds.
