A global conformal extension theorem for perfect fluid Bianchi space-times
Christian Lübbe, Paul Tod
A global extension theorem is established for isotropic singularities in polytropic perfect fluid Bianchi space-times. When an extension is possible, the limiting behaviour of the…

Conditions for nonexistence of static or stationary, Einstein-Maxwell, non-inheriting black-holes
Paul Tod
We consider asymptotically-flat, static and stationary solutions of the Einstein equations representing Einstein-Maxwell space-times in which the Maxwell field is not constant alon…
