Russian Mathematics, 2017
We study a partial case of canonical almost geodesic mappings of the first type of spaces with affine connection that preserve Weyl projective curvature tensor and certain other tensors.

ON M-PROJECTIVE CURVATURE TENSOR OF SASAKIAN MANIFOLDS ADMITTING ZAMKOVOY CONNECTION

, 2020
The purpose of the present paper is to study some properties of Sasakian manifold admitting Zamkovoy connection. We study M− Projectively flat, as well as φ−M−Projectively flat Sasakian manifolds admitting Zamkovoy connection.

Impact of pseudo projective curvature tensor on a space-time and $f(r,G)$-gravity

International Journal of Geometric Methods in Modern Physics (IJGMMP)
In this article, we classify pseudo projectively flat space-times and acquire that it represents either an anti- de-Sitter or de-Sitter space-time. Furthermore, we obtain that a pseudo projectively flat perfect fluid space-time represents dark matter era

Some Curvature Conditions Provided by the Projective Curvature Tensor on the Almost C(?)-Manifold

In this article, the projective curvature tensor on a C (?)-manifold is discussed. Some special curvature conditions provided by the projective curvature tensor on the Riemann, Ricci, concircular curvature tensors have been investigated. As a result of the curvature conditions given with the projective curvature tensor on a C (?)-manifold, cases such ...

\(K\)-contact and Sasakian manifold with conservative projective curvature tensor

2012
The authors deal with contact manifolds whose projective curvature tensor \(P\) is conservative, i.e. \(\text{div} P = 0\). They show that if \(M_{2n + 1} (\varphi, \xi, \eta, g)\) is a \(K\)-contact Riemannian manifold then it is Einstein and \(P (\xi, X) \xi = 0\) for every \(X\), and if \(M_{2n + 1} (\varphi, \xi, \eta, g)\) is a Sasakian manifold ...

On the Weyl projective curvature tensor of an \(N(k)\)-contact metric manifold

2010
The authors classify \(N(k)\)-contact metric manifolds which satisfy the conditions: \[ P(\zeta,X). R=0,\;R(\zeta,X). P=0,\;P(\zeta,X). S=0,\;P(\zeta,X). P=0,\;P(\zeta,X). Z=0, \] where \(P\) is the Weyl projective curvature tensor, \(Z\) is the concircular curvature tensor, \(R\) is the Riemannian- Christoffel curvature tensor and \(S\) is the Ricci ...
