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

Impact of concircular curvature tensor in f(R*)-gravity

Filomat
This paper concerns with the characterization of a spacetime and f (R*)-gravity endowed with concircular curvature tensor. We prove that a concircularly flat perfect fluid spacetime is either a de- Sitter spacetime or locally isometric to Minkowski spacetime.

Concircular Curvature Tensor on Generalized Kenmotsu Manifolds

, 2018
The aim of the present paper is to study on concircular curvature tensor on generalized Kenmotsu manifolds. Concircular flat and φ-concircular flat generalized Kenmotsu manifolds are examined. Also some results are given about φ-semi symmetric and φ -concircular semi symmetric generalized Kenmotsu manifolds.

Semiconformal symmetry- A new symmetry of the spacetime manifold of the general relativity

, 2019
In this paper we have introduced a new symmetry property of spacetime which is named as semiconformal curvature collineation, and its relationship with other known symmetry properties has been established.
