SUMMARY: BTZ/CFT  
DESCRIPTION:Featuring Raman Sundrum\, University of Maryland\n\nPart of the
	 HET Seminar Series.\n\nAbstract: The simplest black hole solution in asymp
	totic AdS spacetime\, the eternal 3-dimensional BTZ black hole\, is studied
	 from the viewpoint of AdS/CFT duality. We identify a class of non-local co
	rrelators on the CFT side that allow us to generalize the notion of quantum
	 gravity "S-matrix" to scattering inside the horizon. Since the interior of
	 the horizon is a cosmological spacetime with a big bang/crunch-like singul
	arity\, our construction can be interpreted as identifying generally coordi
	nate invariant observables of quantum gravity in a simple cosmology\, and t
	heir non-perturbative realization within CFT. We show in a certain precise 
	sense\, that these holographic observables lie "before the big bang" in a r
	egion of spacetime containing closed timelike curves. A central tool in our
	 analysis is the realization of BTZ as a quotient of 3-dimensional AdS.
