The object of the present paper is to study weakly -symmetric and weakly -Ricci symmetric Kenmotsu manifolds. It is shown that weakly -symmetric and weakly -Ricci symmetric Kenmotsu manifolds are -Einstein.

The object of the present paper is to study weakly -symmetric manifolds and its decomposability with the existence of such notions. Among others it is shown that in a decomposable weakly -symmetric manifold both the decompositions are weakly Ricci symmetric.

We prove that if the sectional curvature of an n-dimensional pseudo-symmetric manifold with semi-symmetric metric connection is independent of the orientation chosen then the generator of such a manifold is gradient and also such a manifold is subprojective in the sense of Kagan.
