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 ...
