Special Trans-Sasakian Manifolds and Curvature Conditions [PDF]
, 2012 In this paper a special type of trans-Sasakian manifolds called -trans-Sasakian manifolds are studied. We present some general results for sectional curvatures of higher dimensional -trans-Sasakian manifolds and establish relations among the sectional ...

Lightlike Hypersurfaces of an Indefinite Para Sasakian Manifold
Adıyaman University Journal of Science, 2019 In this paper, we initiate the study of lightlike hypersurfaces of an indefinite 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.

Einstein like $(\varepsilon)$-para Sasakian manifolds
, 2012 Einstein like $(\varepsilon)$-para Sasakian manifolds are introduced. For an $(\varepsilon) $-para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained. The scalar curvature of an Einstein like $(\varepsilon) $-para Sasakian manifold is obtained and it is shown that the scalar ...

A Note on Ricci Solitons on Para-Sasakian Manifolds
Erzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018 In the present paper, in an almost para-contact metric manifold, especially on para-Sasakian manifolds, Ricci solitons were examined. Also, we consider the generalized quasi-conformal curvature tensor on a para-Sasakian manifold admitting Ricci soliton.

, 2008 In the present article we carry on a systematic study of 3-quasi-Sasakian manifolds. In particular, we prove that the three Reeb vector fields generate an involutive distribution determining a canonical totally geodesic and Riemannian foliation. Locally,

Sasakian manifolds and M-theory
, 2016 We extend the link between Einstein Sasakian manifolds and Killing spinors to a class of η-Einstein Sasakian manifolds, both in Riemannian and Lorentzian settings, characterizing them in terms of generalized Killing spinors.

Studies on Sasakian, Lorentzian para (LP)-Sasakian manifold and other related manifolds
, 2007 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 ...

Characterization of Sasakian manifolds [PDF]
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.
