On the global Structure of Robinson–Trautman space-times
The global structure of Robinson–Trautman space-times is studied. When the space-time topology is R + x R x S 2 it is shown that all Robinson–Trautman space-time can be C 117 extended (in the vacuum Robinson–Trautman class of metrics) beyond the r = 2 m 'Schwarzschild-like' event horizon; evidence is …
