Weakly Ricci-Symmetric Space-Times and f (R,G) Gravity
In the present article, we classify conformally flat weakly Ricci-symmetric space-times and obtain that they represent Robertson–Walker space-times. Furthermore, we provethat a Ricci-recurrent weakly Ricci-symmetric space-time is static and a Ricci-semi ...

Quarter-symmetric metric connection in a P-Sasakian manifold
, 2015 In this paper, we consider a quarter-symmetric metric connection in a P-Sasakian manifold. We investigate the curvature tensor and the Ricci tensor of a P-Sasakian manifold with respect to the quarter-symmetric metric connection.

SOME GEOMETRIC PROPERTIES OF PARA-KENMOTSU MANIFOLDS ADMITTING $Q \varphi=\varphi Q$
Hereby, some geometric properties such as $\varphi-$ Ricci symmetric, weakly $\varphi$-Ricci symmetric and Ricci-Yamabe soliton as well as parallel 2-form of the para-Kenmotsu manifolds admitting $Q \varphi=\varphi Q$ are discussed. This paper also deals

THE IMPACT OF SEMI-SYMMETRIC NON-METRIC CONNECTION ON A 3-DIMENSIONAL RIEMANNIAN MANIFOLD ADMITTING SOLITONS [PDF]
This article carries out the investigation of a 3-dimensional Riemannian manifold M^3 endowed with a semi-symmetric type of non-metric connection. After introduction, we provide the basic results of semi-symmetric non-metric connection.

A study on generalized Einstein tensor for an almost pseudo-ricci symmetric manifold
, 2022 The object of the paper is to study the generalized Einstein tensor G(X,Y) on almost pseudo-Ricci symmetric manifolds, A(PRS)n. Considering the generalized Einstein tensor G(X,Y) as conservative, cyclic parallel and Codazzi type, it is investigated the ...

Ricci semi-symmetric normal complex contact metric manifolds
, 2020 In this paper, we obtain the necessary and sufficient conditions a complex almost contact metric manifold to be normal. In addition, we give some new identities for the Riemann curvature and the Ricci curvatures of normal complex contact metric manifolds.
