Comment on Counting Black Hole Microstates Using String Dualities
arXiv:hep-th/0312164 · doi:10.1103/PhysRevD.70.026007
Abstract
We discuss a previous attempt at a microscopic counting of the entropy of asymptotically flat non-extremal black-holes. This method used string dualities to relate 4 and 5 dimensional black holes to the BTZ black hole. We show how the dualities can be justified in a certain limit, equivalent to a near horizon limit, but the resulting spacetime is no longer asymptotically flat.
