Dual brane pairs and the Bekenstein-Hawking entropy of non-Susy spacetimes

A novel approach is described towards a microscopic understanding of the Bekenstein-Hawking entropy of non-supersymmetric spacetimes-including the Schwarzschild black hole. It is based at an intermediate step on the description of the event horizon in terms of dual Euclidean brane pairs of type-II string theory or M theory. By counting specific chain structures on the brane complex, it is shown that one can reproduce the exact Schwarzschild black hole entropy plus its logarithmic correction.
