On three-dimensional trans-Sasakian manifolds [PDF]

open access: yes, 2008
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.

Curvature Properties of Quasi-Para-Sasakian Manifolds [PDF]

open access: yes, 2019
The paper is devoted to study quasi-para-Sasakian manifolds. Basic properties of such manifolds are obtained and general curvature identities are investigated. Next it is proved that if M is a quasi-para-Sasakian manifold of constant curvature K. Then K

Immersions of Sasaki–Ricci solitons into homogeneous Sasakian manifolds [PDF]

open access: yes
We discuss local Sasakian immersion of Sasaki-Ricci solitons (SRS) into fiber products of homogeneous Sasakian manifolds. In particular, we prove that SRS locally induced by alarge class of fiber products of homogeneous Sasakian manifolds are, in fact ...

Hypersurfaces of Lorentzian para-Sasakian manifolds [PDF]

open access: yes, 2011
In this paper we study the invariant and noninvariant hypersurfaces of $(1,1,1)$ almost contact manifolds, Lorentzian almost paracontact manifolds and Lorentzian para-Sasakian manifolds, respectively.

Ricci Solitons in (ε,δ)-Trans-Sasakian Manifolds

open access: yesInternational 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.

A Note on Rigidity of 3-Sasakian Manifolds [PDF]

open access: yes, 1998
Making use of the relations among 3-Sasakian manifolds, hypercomplex manifolds and quaternionic Kahler orbifolds, we prove that complete 3-Sasakian manifolds are rigid. Keywords: Sasakian, Hypercomplex, Deformations.

Einstein like -para Sasakian manifolds [PDF]

open access: yes, 2013
Einstein like  -para Sasakian manifolds are introduced. For an  -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.
