Pseudo projective curvature tensor satisfying some properties on a normal paracontact metric manifold

, 2018
In the present paper we have studied the curvature tensor of a normal paracontact metric manifold satisfying the conditions R(ξ,X)P=0, P(ξ,X)R=0, P(ξ,X)P=0, P(ξ,X)S=0, P(ξ,X)Z=0 and pseudo projective flatness, where R, P, S and Z denote the Riemannian ...

A Note On The Quasi-Conformal And M-Projective Curvature Tensor Of A Semi-Symmetric Recurrent Metric Connection On A Riemannian Manifold

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2013
: In the present note we have considered Mn to be a Riemannian manifold admitting a semi-symmetric recurrent metric connection. The aim of the present paper is to obtain the conditions under which the quasi-conformal curvature tensor and M-projective ...

On a Class of P-Kenmotsu Manifolds Admitting Weyl-projective Curvature Tensor of Type (1, 3)

Turkish Journal of Analysis and Number Theory, 2019
We study a class of para-Kenmotsu manifolds admitting Weyl-projective curvature tensor of type (1, 3). At the end, it is shown that an n-dimensional (n > 2) P-Kenmotsu manifold is Ricci semisymmetric if and only if it is an Einstein manifold.

Impact of projective curvature tensor in f(R,G), f(R,T) and f(R,Lm)-Gravity [PDF]

International Journal of Geometric Methods in Modern Physics (IJGMMP), 2023
This article concerns with the characterization of a spacetime and modified gravity, such as $f\left(R,G\right)$, $f\left(R,T\right)$ and $f\left(R,L_{m}\right)$-gravity equipped with the projective curvature tensor. We establish that a projectively flat

Conditions on the projective curvature tensor of hypersurfaces in euclidian space [PDF]

Annales de la Faculté des sciences de Toulouse : Mathématiques, 1985
Hypersurfaces of Euclidean space satisfying certain conditions on the projective curvature tensor are studied and local characterizations of certain types of immersions are obtained. A characterization is given of certain hypersurfaces of revolution that are, in the 3-dimensional case, generalizations of the catenoid.
