研究了4d N=2规范超引力中AdS 4中静态双子BPS黑洞的熵，并讨论了如何在AdS/CFT双场论中用微观态计数再现熵.我们研究了一个特殊的例子，即AdS 4 ×S6的BPS黑洞，它的对偶三维边界描述是已知的，并且是简单的。为了计算场论中的状态，我们采用了一个超对称的拓扑扭曲指数，它可以用局域化技术精确计算。我们找到了一个完美的匹配。
We study the entropy of static dyonic BPS black holes in AdS4 in 4d N=2 gauged supergravities with vector and hyper multiplets, and how the entropy can be reproduced with a microscopic counting of states in the AdS/CFT dual field theory. We focus on the particular example of BPS black holes in AdS4×S6 in massive Type IIA, whose dual three-dimensional boundary description is known and simple. To count the states in field theory we employ a supersymmetric topologically twisted index, which can be computed exactly with localization techniques. We find a perfect match at leading order.
