Pseudo Conharmonically Symmetric Spacetimes
Zengin, Füsun Özen; Taşçı, Ayşe Yavuz (Univ Kragujevac, Fac Science, 2018)In the present paper, firstly, the definition of pseudo conharmonically symmetric Riemannian manifold is given. In the second section, some theorems about these manifolds are proved. In the third section, pseudo conharmonically ... -
Spacetimes admitting the Z-symmetric tensor
Zengin, Füsun Özen; Taşçı, Ayşe Yavuz (Natl Inquiry Services Centre Pty Ltd, 2020)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 ... -
Z-symmetric manifold admitting concircular Ricci symmetric tensor
Taşçı, Ayşe Yavuz; Zengin, Füsun Özen (Springer Heidelberg, 2020)This paper deals with Z-symmetric Riemannian manifolds with concircular Ricci symmetric tensor. In the first section, we give an introduction of Z-symmetric manifold. In the second section, the definition of concircular ...
