Spherically symmetric Anti-de Sitter-like Einstein-Yang-Mills spacetimes
C. Lübbe, J. A. Valiente Kroon
The conformal field equations are used to discuss the local existence of spherically symmetric solutions to the Einstein-Yang-Mills system which behave asymptotically like the anti…
On the conformal structure of the extremal Reissner-Nordström spacetime
Christian Lübbe, Juan A. Valiente Kroon
We analyse various conformal properties of the extremal Reissner-Nordström spacetime. In particular, we obtain conformal representations of the neighbourhoods of spatial infinity,…
A class of conformal curves in the Reissner-Nordström spacetime
Christian Lübbe, J. A. Valiente Kroon
A class of curves with special conformal properties (conformal curves) is studied on the Reissner-Nordström spacetime. It is shown that initial data for the conformal curves can be…
A conformal approach for the analysis of the non-linear stability of pure radiation cosmologies
C. Lübbe, J. A. Valiente Kroon
The conformal Einstein equations for a tracefree (radiation) perfect fluid are derived in terms of the Levi-Civita connection of a conformally rescaled metric. These equations are…
An extension theorem for conformal gauge singularities
Christian Lübbe, Paul Tod
We analyse conformal gauge, or isotropic, singularities in cosmological models in general relativity. Using the calculus of tractors, we find conditions in terms of tractor curvatu…
