QUASI-CONFORMAL CURVATURE TENSOR OF GENERALIZED SASAKIAN-SPACE-FORMS [PDF]

, 2020
The present paper deals the study of generalised Sasakian-space-forms with the conditions Cq(ξ,X).S = 0, Cq(ξ,X).R = 0 and Cq(ξ,X).Cq = 0, where R, S and Cq denote Riemannian curvature tensor, Ricci tensor and quasi-conformal curvature tensor of the ...

Semi-Symmetric Generalized Sasakian Space Forms On Some Special Curvature Tensors

, 2022
In this article, semi-symmetric generalized Sasakian space forms are investigated on some special curvature tensors. Characterizations of generalized Sasakian space forms are obtained on some specially selected ??curvature tensors.

Locally conformal C6-manifolds and generalized Sasakian-space-forms

, 2010
An algebraic characterization of generalized Sasakian-space-forms is stated. Then, one studies the almost contact metric manifolds which are locally conformal to $C_6$-manifolds, simply called l.c. $C_6$-manifolds.

Legendrian warped product submanifolds in generalized Sasakian space forms

, 2009
Recently, K. Matsumoto and I. Mihai established a sharp inequality for warped products isometrically immersed in Sasakian space forms. As applications, they obtained obstructions to minimal isometric immersions of warped products into Sasakian space ...

Integral surfaces of Sasakian space forms

Journal of Geometry, 1992
Let \(M(k)\) be a 5-dimensional Sasakian space form with characteristic vector field \(\xi\), and \(M\) an integral surface of \(M(k)\). The mean curvature vector \(H\) of \(M\) is said to be \(C\)-parallel if \(\nabla H\) is parallel to \(\xi\). The authors determine integral surfaces of \(M(k)\) with \(C\)-parallel mean curvature vector.

Generalized Sasakian space forms on \(W_0\)-curvature tensor

, 2023
Summary: In this article, generalized Sasakian space forms are investigated on \(W_0\)-curvature tensor. Characterizations of generalized Sasakian space forms are obtained on \(W_0\)-curvature tensor. Special curvature conditions established with the help of Riemann, Ricci, concircular, projective curvature tensors are discussed on \(W_0\)-curvature ...

Slant Submersions in Generalized Sasakian Space Forms and Some Optimal Inequalities

Axioms
This research examines key inequalities associated with the scalar and Ricci curvatures of slant submersions within generalized Sasakian space forms (GSSFs). We establish significant geometric constraints and conduct a detailed analysis of the conditions
