Modified brane cosmologies with induced gravity, arbitrary matter content and a Gauss-Bonnet term in the bulk
Pantelis S. Apostolopoulos, Nikolaos Brouzakis, Nikolaos Tetradis +1
We extend the covariant analysis of the brane cosmological evolution in order to take into account, apart from a general matter content and an induced-gravity term on the brane, a…

Ricci and Matter inheritance collineations of Robertson-Walker space-times
Pantelis S. Apostolopoulos, Michael Tsamparlis
It is well known that every Killing vector is a Ricci and Matter collineation. Therefore the metric, the Ricci tensor and the energy-momentum tensor are all members of a large fami…
