On the Conharmonic Curvature Tensor of Generalized Sasakian‐Space‐Forms

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
The object of the present paper is to characterize generalized Sasakian‐space‐forms satisfying certain curvature conditions on conharmonic curvature tensor. In this paper we study conharmonically semisymmetric, conharmonically flat, ξ‐conharmonically flat, and conharmonically recurrent generalized Sasakian‐space‐forms.

Chen optimal inequalities of CR-warped products of generalized Sasakian space form

Journal of Taibah University for Science, 2020
Our main objective of this paper is to derive the relationship between the main extrinsic invariant, and the contact CR δ-invariant (new intrinsic invariant) on a generic submanifold in trans-Sasakian generalized Sasakian space forms.

On pseudo-slant submanifolds of nearly trans-Sasakian manifolds [PDF]

, 2014
This paper consist the study of pseudo-slant submanifolds of nearly trans-Sasakian manifolds. Integrability conditions of the distributions on these submanifolds are worked out. Some interesting results regarding such manifolds have also been deduced. An

A remark on trans-Sasakian 3-manifolds [PDF]

Revista de la Unión Matemática Argentina, 2019
Summary: Let \(M\) be a trans-Sasakian 3-manifold of type \((\alpha, \beta)\). In this paper, we give a negative answer to the question proposed by \textit{S. Deshmukh} [Mediterr. J. Math. 13, No. 5, 2951--2958 (2016; Zbl 1359.53022)], namely we prove that the differential equation \(\nabla \beta = \eta(\beta)\eta\) on \(M\) does not necessarily imply ...

η-RICCI SOLITONS IN (ϵ,δ)-TRANS SASAKIAN MANIFOLDS [PDF]

, 2019
The object of the present research is to study the (ϵ,δ)-TransSasakian manifolds addmitting the η-Ricci Solitons. It is shown that a sym-metric second order covariant tensor in an (ϵ,δ)-Trans Sasakian manifold isa constant multiple of metric tensor. Also

Clairaut anti-invariant Riemannian maps to trans-Sasakian manifolds [PDF]

, 2023
In this article, we introduce Clairaut anti-invariant Riemannian maps from Riemannian manifolds to trans-Sasakian manifolds. We derive necessary and sufficient condition for an anti-invariant map to be Clairaut when base manifold is trans-Sasakian ...

Ricci Solitons in f-Kenmotsu Manifolds and 3-dimensional Trans-Sasakian Manifolds [PDF]

, 2012
In the Present paper we study Ricci solitons in trans-sasakian manifolds. In particular we consider Ricci solitons in f -Kenmotsu manifolds and we prove the conditions for the Ricci solitons to be shrinking, steady and expanding.Key words: Ricci solitons;

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 ...
