On contact CR‐submanifolds of sasakian manifolds [PDF]
International Journal of Mathematics and Mathematical Sciences, 1983 Recently, K.Yano and M.Kon [5] have introduced the notion of a contact CR‐submanifold of a Sasakian manifold which is closely similar to the one of a CR‐submanifold of a Kaehlerian manifold defined by A. Bejancu [1].In this paper, we shall obtain some fundamental properties of contact CR‐submanifolds of a Sasakian manifold. Next, we shall calculate the

A Class of Lorentzian α-Sasakian Manifolds
Kyungpook mathematical journal, 2009 In this study we consider φ conformally at, φ conharmonically at, φ projectively at and φ concircularly at Lorentzian α Sasakian manifolds. In all cases, we get the manifold will be an η Einstein manifold.

Turkish Journal of Mathematics, 2013 In this study, almost contact Finsler structures on vector bundle are defined and the condition of normality in terms of the Nijenhuis torsion Nf of almost contact Finsler structure is obtained. It is shown that for a K-contact structure on Finsler manifold \nablaX x =-\frac{1}{2} f X and the flag curvature for plane sections containing x are equal to \

The local moduli of Sasakian 3-manifolds
International Journal of Mathematics and Mathematical Sciences, 2002 The Newman-Penrose-Perjes formalism is applied to Sasakian 3-manifolds and the local form of the metric and contact structure is presented. The local moduli space can be parameterised by a single function of two variables and it is shown that, given ...

Deformation of a Sasakian Manifold
Journal of the Tensor Society, 2008 A contact Structure on a Brieskorn manifold is studied by K. Abe [1] and S. Saki and C.S. Hsu[2], K. Abe [1] proved that there exist Sasakian structure on Brieskorn manifold. We apply these deformation on the standard Sasakian spheres and show that Brieskorn manifold have atmost contact metric manifold so that Brieskorn manifolds are invariant ...

Ricci Solitons in (ε,δ)-Trans-Sasakian Manifolds
International Journal of Analysis and Applications, 2017 We study Ricci solitons in (ε,δ)-trans-Sasakian manifolds. It is shown that a symmetric parallel second order covariant tensor in a (ε,δ)-trans-Sasakian manifold is a constant multiple of the metric tensor.
