Monsters in AdS

Slides I used for the workshop discussion yesterday: What Part of the Asymptotically AdS Gravitational Phase Space is Dual to a CFT?

In classical general relativity one can construct configurations with fixed ADM mass but arbitrarily large entropy. These objects collapse into black holes but have more entropy than the area of the resulting black hole. Their interpretation in quantum gravity and in the AdS/CFT duality is an open question.

This topic is also nicely discussed by Don Marolf here and here.

It was great to have Bill Unruh in the audience, whom I had never met in person before.

Thanks for the links... Too bad I couldn't make it to the KITP program :o( I think the question is one that hasn't really received enough attention. Any chance you'll write a longer blogpost on it?

I might write something if time permits. In the mean time, the workshop wiki is pretty good and the videos are quite watchable.
