String theory formulation of the threedimensional black hole
Abstract
A black hole solution to threedimensional general relativity with a negative cosmological constant has recently been found. We show that a slight modification of this solution yields an exact solution to string theory. This black hole is equivalent (under duality) to the previously discussed threedimensional black string solution. Since the black string is asymptotically flat and the black hole is asymptotically antide Sitter, this suggests that strings are not affected by a negative cosmological constant in three dimensions.
