On nearly Sasakian and nearly cosymplectic manifolds
We prove that every nearly Sasakian manifold of dimension greater than five is Sasakian. This provides a new criterion for an almost contact metric manifold to be Sasakian.

Studies on Sasakian, Lorentzian para (LP)-Sasakian manifold and other related manifolds
Ph.d ThesisThe study of tensors in differentiable manifolds that vary in structure have attracted many researchers. In this thesis out of many newly defined tensors W2 -curvature tensor and W4 -curvature tensor have been studied in Sasaki an, Para ...

Lightlike hypersurfaces of an $(\epsilon)$-para Sasakian manifold
In this paper, we initiate the study of lightlike hypersurfaces of an $(\epsilon)$-almost paracontact metric manifold which are tangent to the structure vector field. In particular, we give definitions of invariant lightlike hypersurfaces and screen semi-invariant lightlike hypersurfaces, and give some examples.

Characterization of Sasakian manifolds
Weak contact metric manifolds, i.e., the linear complex structure on the contact distribution is replaced by a nonsingular skew-symmetric tensor, defined by the author and R. Wolak, allowed us to take a new look at the theory of contact manifolds.

We define a new class of manifolds called $n$-Sasakian manifolds that enjoy remarkable geometric properties. We furnish examples of such manifolds and make links to the study of isoparametric hypersurfaces.

On three-dimensional trans-Sasakian manifolds
The object of the present paper is to study 3-dimensional trans-Sasakian manifolds which are locally Á-symmetric and have ´-parallel Ricci tensor. Also 3-dimensional trans- Sasakian manifolds of constant curvature have been considered.
