Generalized Robertson-Walker space times, a survey
Carlo Alberto Mantica, Luca Guido Molinari
Generalized Robertson-Walker spacetimes extend the notion of Robertson-Walker spacetimes, by allowing for spatial non-homogeneity. A survey is presented, with main focus on Chen's…

A note on extended Lorentzian recurrent manifolds
Carlo Alberto Mantica, Luca Guido Molinari
Extended recurrent pseudo-Riemannian manifolds were introduced by Mileva Prvanovic'. We reconsider her work in the light of recent results and show that the manifold is conformally…

On the Weyl and Ricci tensors of Generalized Robertson-Walker space-times
Carlo Alberto Mantica, Luca Guido Molinari
We prove theorems about the Ricci and the Weyl tensors on generalized Robertson-Walker space-times of dimension . In particular, we show that the concircular vector introdu…
