AdS not globally hyperbolic

  1. Apr 3, 2012 #1
    Is there an easy way to see this? can it be see via the penrose diagram? does it have anything to do with how when a stone is thrown in AdS it will alwayscome backk in finite time..

    I'm not familiar with AdS spaces, but according to the Wikipedia page, it says that these spaces have closed time-like curves. Any manifold with closed time-like curves cannot be globally hyperbolic.

    Have a look at Hawking and Ellis.
