Lie Groups of Conformal Motions acting on Null Orbits
(Carot, Jaume; Coley, A. A.; Sintes, A. M.)
Abstract
Space-times admitting a 3-dimensional Lie group of conformal motions acting on null orbits containing a 2-dimensional Abelian subgroup of isometries are studied. Coordinate expressions for the metric and the conformal Killing vectors (ckv) are provided (irrespective of the matter content) and then all possible perfect fluid solutions are found, although none of these verify the weak and dominant energy conditions over the whole space-time manifold.
