Conformal symmetries in warped manifolds
(P. S., Apostolopoulos; Carot, Jaume.)
Abstract
The existence of a Conformal Vector Field (CVF) is studied in the important class
of warped manifolds of arbitrary dimension ...

Scalar field cosmologies: a dynamical systems study
(Carot, Jaume; Collinge, Magdalena M.)
Abstract
Inhomogeneous G2 solutions whose material content can be modelled by a scalar field are considered with a view towards ...
Scalar field spacetimes

Scalar field spacetimes
(Carot, Jaume; Collinge, Magdalena M.)
Abstract
Scalar field spacetimes are considered with a view towards their applications in cosmology. Some results existing in the literature are reviewed ...

On the geometry of warped spacetimes
(Carot, Jaume; da Costa, J.)
Abstract
An invariant characterization of warped spacetimes is given and a classification scheme for them is proposed. Some results on the curvature ...

(SABER ULA, 2008-07-02)
Energy-momentum types of warped spacetimes
(Carot, Jaume; Haddow, Barry M.
Abstract
The possible energy–momentum types of warped product pacetime are investigated using the classification given by Carot and da Costa.
Some developments on axial symmetry
(SABER ULA, 2008-07-02)
Some developments on axial symmetry
(Carot, Jaume)
Abstract
The definition of axial symmetry in general relativity is reviewed, and some results concerning the geometry in a neighbourhood of the axis are derived. ...

Conformally reducible 2 + 2 spacetimes
(Carot, Jaume; Tupper, Brian O. J.)
Abstract
Spacetimes which are conformal to 2 + 2 reducible spacetimes are considered. We classify them according to their conformal algebra, ...
