论文摘要
众所周知，渐近平坦的四维Kerr黑洞的熵比同一质量的Schwarzschild黑洞较小（特异性）。我们在这里表明，如果固定温度而不是质量，则相同。而且我们还表明，渐近广告$ _5 $ -KERR黑洞的特定熵比ADS $ _5 $ -Schwarzschild Black Hole的特定熵较小，除了可以忽略不计的特殊示例少。广告$ _5 $ -KERR案件特别有趣，因为在这里适用了仪表奖励双重性；如果我们进一步接受对广告黑洞的双重耦合场理论与强烈耦合流体的最佳示例（夸克 - 格鲁恩等离子体）之间有一个有用的类比，那么在这种情况下，我们可以应用QGP理论来预测黑洞入口的行为。该预测与我们对广告$ _5 $ -KERR熵的研究一致。希望这样的结果可能最终导致黑洞微杆菌的鉴定。
It is well known that an asymptotically flat four-dimensional Kerr black hole has a smaller (specific) entropy than a Schwarzschild black hole of the same mass. We show here that the same is true if the temperature, rather than the mass, is held fixed; and we also show that an asymptotically AdS$_5$-Kerr black hole has a smaller specific entropy than an AdS$_5$-Schwarzschild black hole of the same temperature, except in a negligibly small class of special examples. The AdS$_5$-Kerr case is particularly interesting, because here the gauge-gravity duality applies; if we further accept that there is a useful analogy between the strongly coupled field theories dual to AdS black holes and the best-understood example of a strongly coupled fluid (the Quark-Gluon Plasma), then we can apply QGP theory to predict the behaviour of black hole entropy in this case. The prediction agrees with our study of AdS$_5$-Kerr entropy. The hope is that such results might lead ultimately to an identification of black hole microstates.
