The paper aims to investigate curvature inheritance symmetry in M-projectively flat spacetimes. It is shown that the curvature inheritance symmetry in M-projectively flat spacetime is a conformal motion. We have proved that M- projective curvature te

This paper aims to introduce the spacetimes admitting the Z-symmetric tensor. We investigate the properties of these spacetimes for a perfect fluid and a pressureless perfect fluid (a dust). Some theorems about the properties are proved.

Applications of a Special Generalized Quasi-Einstein Manifold

Autor: Bahar Kırık, Füsun Özen Zengin

Publikováno v: Bulletin of the Iranian Mathematical Society. 45:89-102

In this paper, we work on some properties of generalized quasi-Einstein and pseudo Ricci symmetric generalized quasi-Einstein manifolds. Firstly, some basic concepts about generalized quasi-Einstein manifolds are given. In the second section, the hol

ON M-Projectively Flat LP-Sasakian Manifolds

Autor: Füsun Özen Zengin

Publikováno v: Ukrainian Mathematical Journal. 65:1725-1732

In the present paper, we study the nature of LP-Sasakian manifolds admitting the M-projective curvature tensor. It is examined whether this manifold satisfies the condition W(X, Y ).R = 0. Moreover, it is proved that, in the M-projectively flat LP-Sa
