An extension of the Newman-Janis algorithm
Aidan J. Keane
The Newman-Janis algorithm is supplemented with a null rotation and applied to the tensors of the Reissner-Nordström spacetime to generate the metric, Maxwell, Ricci and Weyl tenso…
Conformally reducible 1+3 spacetimes
Jaume Carot, Aidan J Keane, Brian O J Tupper
Spacetimes which are conformally related to reducible 1+3 spacetimes are considered. We classify these spacetimes according to the conformal algebra of the underlying reducible spa…
Conformal symmetry classes for pp-wave spacetimes
Aidan J Keane, Brian O J Tupper
We determine conformal symmetry classes for the pp-wave spacetimes. This refines the isometry classification scheme given by Sippel and Goenner (1986 {\it Gen. Rel. Grav.} {\bf 18}…
A classification of spherically symmetric spacetimes
Brian O. J. Tupper, Aidan J. Keane, Jaume Carot
A complete classification of locally spherically symmetric four-dimensional Lorentzian spacetimes is given in terms of their local conformal symmetries. The general solution is giv…
Killing tensors in pp-wave spacetimes
Aidan J Keane, Brian O J Tupper
The formal solution of the second order Killing tensor equations for the general pp-wave spacetime is given. The Killing tensor equations are integrated fully for some specific pp-…
The Conformal Group SO(4,2) and Robertson-Walker Spacetimes
Aidan J. Keane, Richard K. Barrett
The Robertson-Walker spacetimes are conformally flat and so are conformally invariant under the action of the Lie group SO(4,2), the conformal group of Minkowski spacetime. We find…
