Perfect-fluid, generalised Robertson-Walker space-times, and Gray's decomposition
Carlo Alberto Mantica, Luca Guido Molinari, Young Jin Suh +1
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-times, we deter…

Ricci solitons on singly warped product manifolds and applications
Uday Chand De, Carlo Alberto Mantica, Sameh Shenawy +1
The purpose of this article is to study implications of a Ricci soliton warped product manifold to its base and fiber manifolds. First, it is proved that if a warped product manifo…
