Symmetry and pseudosymmetry properties with Ricci soliton of the Reissner-Nordström-de Sitter spacetime

Nuclear Physics B
The primary objective of the article is to investigate the symmetry and pseudosymmetry properties of the Reissner-Nordström-de Sitter (briefly, RNdS) spacetime. The secondary aim of the paper is to explore the notion of Ricci solitons in RNdS spacetimes.

Journal of Hyperstructures
In this paper we prove some curvature properties of anti-invariant submanifold of Lorentzian para-Kenmotsu manifold (briefly, LP-Kenmotsu manifolds) with respect to Zamkovoy connection (∇∗).

On Concircular Curvature Tensor and Curvature Identities of C_5⊕C_12-Manifolds

Basrah Journal of Science
In this article, we determine the necessary and sufficient condition that makes -manifold classified as almost -manifold. We discover   -manifold belongs to the class  and then to the class  because  , however, this manifold does not belong to the class  unless its dimension is 3, or it rounds to -manifold.

PERFECT FLUID SPACETIMES WITH HARMONIC GENERALIZED CURVATURE TENSOR [PDF]

We show that n-dimensional perfect fluid spacetimes with divergence-free conformal curvature tensor and constant scalar curvature are generalized RobertsonWalker (GRW) spacetimes; as a consequence a perfect fluid Yang pure space is a GRW spacetime.

On Almost C(?)- Manifold Satisfying Some Curvature Conditions on the D-Conformal Curvature Tensor

, 2022
In this study, the C(α)-manifold is discussed together with the D-conformal curvature tensor. The properties of the C(α)-manifold on the D-conformal curvature tensor compared to Riemann, Ricci, concircular and quasi-conformal curvature tensors is ...

Ricci–Yamabe Solitons on Sasakian Manifolds with the Generalized Tanaka–Webster Connection

AppliedMath
In this article, we analyze some curvature restrictions satisfying by the concircular curvature tensor in (2n+1)-dimensional Sasakian manifolds with the generalized Tanaka–Webster connection ∇¯ admitting Ricci–Yamabe solitons. Finally, we give an example

Pseudosymmetry and curvature inheritance of the interior black hole spacetime

Physics Letters B
The notion of pseudosymmetry by Adamów and Deszcz [1] generalizes the concept of local symmetry and semisymmetry, and it serves as a model of various spacetimes. The classification of pseudosymmetric spacetimes has been studied in [2].
