String theory and black holes
Abstract
An exact conformal field theory describing a black hole in twodimensional spacetime is found as an SL(2,openR)/U(1) gauged WessZuminoWitten model. For k=9/4, the conformal field theory can be regarded as a classical solution of the same system that is probed in the c=1 matrix model. The conformal field theory governing the spacetime is regular at the Riemannian singularity, but it appears that generic perturbations blow up there. It is argued that the end point of the Hawking blackhole evaporation is the standard spacetime of the c=1 matrix model, which should be regarded as an analog of the extreme ReissnerNordström black hole of fourdimensional general relativity. The c=1 model is thus a model of the quantum mechanics of matter interacting with a black hole.
