Levy [11] had proved that a second order symmetric parallel non singular tensor on a space of constant curvature is a constant multiple of the metric tensor. Sharma [6] has proved that second order parallel tensor in a Kaehler Space of constant holomorphic sectional curvature is a linear combination with constant coefficients of the Kaehlerian metric and… (More)

The horizontal and complete lifts from a manifold Mn to its cotangent bundles ∗ T(Mn) were studied by Yano and Ishihara, Yano and Patterson, Nivas and Gupta, Dambrowski, and many others. The purpose of this paper is to use certain methods by which fλ(7,1)structure in Mn can be extended to ∗ T(Mn). In particular, we have studied horizontal and complete lifts… (More)

The purpose of this paper is to study invariant submanifolds of an ndimensional manifold M endowed with an F -structure satisfying FK + (−)K+1F = 0 and FW + (−)W+1F ≠ 0 for 1 < W < K, where K is a fixed positive integer greater than 2. The case when K is odd (≥ 3) has been considered in this paper. We show that an invariant submanifold M̃ , embedded in an F… (More)
