Some Curvature Properties on Lorentzian Generalized Sasakian-Space-Forms

Advances in Mathematical Physics, 2019
In this paper, we investigate the Lorentzian generalized Sasakian-space-form. We give the necessary and sufficient conditions for the Lorentzian generalized Sasakian-space-form to be projectively flat, conformally flat, conharmonically flat, and Ricci ...

Bi-$f$-Harmonic Legendre Curves on $(\alpha,\beta)$-Trans-Sasakian Generalized Sasakian Space Forms

Journal of New Theory
In this study, we consider bi-$f$-harmonic Legendre curves on $(\alpha,\beta)$-trans-Sasakian generalized Sasakian space form. We provide the necessary and sufficient conditions for a Legendre curve to be bi-$f$-harmonic on $(\alpha,\beta)$-trans ...

A characterization of Sasakian space forms by the spectrum

Journal of Geometry and Physics, 2015
Let $(M,g)$ and $(M',g')$ be two compact connected smooth Riemannian manifolds without boundaries. Denote by $\mathrm{Spec}^p(M,g)$ (resp. $\mathrm{Spec}^p(M',g')$) the spectrum of the Laplace-Beltrami operator on $p$-forms on $(M,g)$ (resp. $(M',g'))$.

Almost $\eta-$Ricci Solitons on Pseudosymmetric Lorentz Sasakian Space Forms

Communications in Advanced Mathematical Sciences, 2023
In this paper, we consider pseudosymmetric Lorentz Sasakian space forms admitting almost $\eta-$Ricci solitons in some curvature tensors. Ricci pseudosymmetry concepts of Lorentz Sasakian space forms admits $\eta-$Ricci soliton have introduced according ...

Generalized Sasakian space forms with semi-symmetric non-metric connections; pp. 251–257 [PDF]

Proceedings of the Estonian Academy of Sciences, 2011
We introduce generalized Sasakian space forms with semi-symmetric non-metric connections. We show the existence of a generalized Sasakian space form with a semi-symmetric non-metric connection and give some examples by warped products endowed with semi ...

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.

A Note on Nearly Sasakian Manifolds

Mathematics, 2023
A class of nearly Sasakian manifolds is considered in this paper. We discuss the geometric effects of some symmetries on such manifolds and show, under a certain condition, that the class of Ricci semi-symmetric nearly Sasakian manifolds is a subclass of
