  author={Igor R. Klebanov and A. A. Tseytlin},
We carry out a thorough survey of entropy for a large class of p-branes in various dimensions. We find that the Bekenstein-Hawking entropy may be given a simple world volume interpretation only for the non-dilatonic p-branes, those with the dilaton constant throughout spacetime. The entropy of extremal non-dilatonic p-branes is non-vanishing only for the solutions preserving 1/16 or 1/8 of the original supersymmetries. Upon toroidal compactification these reduce to dyonic black holes in 4 and 5… CONTINUE READING
