Maximin surfaces, and the strong subadditivity of the covariant holographic entanglement entropy (2012, background): “This condition parallels the definition of global hyperbolicity [24], except at the AdS boundary, which is not globally hyperbolic by the usual definition.”
The causal hierarchy of spacetimes (2006, background): “(1) As stressed in [8], the full consistency of the causal ladder yields that any globally hyperbolic spacetime is not only causally simple but also strongly causal.”
