Generalized Robertson–Walker spacetimes extend the notion of Robertson–Walker
spacetimes, by allowing for spatial non-homogeneity. A survey is presented, with main focus …

We show that an n-dimensional generalized Robertson–Walker (GRW) space-time with
divergence-free conformal curvature tensor exhibits a perfect fluid stress–energy tensor for …

We prove theorems about the Ricci and the Weyl tensors on Generalized Robertson-Walker
space-times of dimension n≥ 3. In particular, we show that the concircular vector introduced …

We give new necessary and sufficient conditions on the Weyl tensor for generalized
Robertson-Walker (GRW) space-times to be perfect-fluid space-times. For GRW space …

The primary focus of the current study is to explore the geometrical properties of the Vaidya-
Bonner-de Sitter (briefly, VBdS) spacetime, which is a generalization of Vaidya-Bonner …

The aim of this paper is to investigate some geometric and physical properties of the
generalized quasi Einstein spacetime G (QE) 4 under certain conditions. Firstly, we prove …

This paper is devoted to the study of curvature properties of Hayward black hole (briefly,
HBH) spacetime, which is a solution of Einstein field equations (briefly, EFE) having non …

The objective of this article is to study topologically charged Eddington-inspired Born–Infeld
(briefly, EiBI) gravity spacetime. It is proved that the topologically charged EiBI spacetime …

In this paper we have investigated the curvature restricted geometric properties of the
generalized Kantowski–Sachs (briefly, GK–S) spacetime metric, a warped product of 2 …
