Global extensions of spacetimes describing asymptotic final states of black holes
Global extensions of spacetimes describing asymptotic final states of black holes
We consider a globally hyperbolic, stationary spacetime containing a black hole but no white hole. We assume, further, that the event horizon, $\tn$, of the black hole is a Killing horizon with compact cross-sections. We prove that if surface gravity is non-zero constant throughout the horizon one can {\it globally} …
