%0 Journal Article %T Three-Dimensional Extremal Black Holes and the Maldacena Duality %A Naoto Yokoi %A Toshio Nakatsu %J Physics %D 1999 %I arXiv %R 10.1143/PTP.104.439 %X We discuss the microscopic states of the extremal BTZ black holes. Degeneracy of the primary states corresponding to the extremal BTZ black holes in the boundary N=(4,4) SCFT is obtained by utilizing the elliptic genus and the unitary representation theory of N=4 SCA. The degeneracy is consistent with the Bekenstein-Hawking entropy. %U http://arxiv.org/abs/hep-th/9912096v2
