论文摘要
在标准全息``字典''中，通过检查一个简单的Ads-Reissner-NordströmBlackHole的事件地平线附近的大块区域，研究了强烈耦合边界场理论的深度。最近Horowitz等。认为这是不正确的，\ emph {除}的情况下，在小圆环黑洞的情况下，这是特别有趣和重要的。另一方面，弱的重力猜想假设，黑洞（包括环形黑洞）非常接近极端，从而自发地发出了同类的黑洞。我们表明，在感谢您的情况下，这些``发射''黑洞总是很小。作为应用程序，我们讨论了在ADS-REISSNER-NORDSTRöm黑洞之外评估的单点函数方式的Grinberg-Maldacena分析，取决于从事件视野到Cauchy Horizon的适当时间。我们发现，对于发射的环形黑洞，这种依赖性有效地退出。
In the standard holographic ``dictionary'', the deep infrared of the strongly coupled boundary field theory is studied by examining the bulk region near to the event horizon of a simple AdS-Reissner-Nordström black hole, near to extremality. Recently Horowitz et al. have argued that this is not correct, \emph{except} in the case of small toroidal black holes, which are therefore revealed to be particularly interesting and important. On the other hand, the Weak Gravity Conjecture postulates that black holes (including toroidal black holes) which are extremely near to extremality spontaneously emit black holes of the same kind. We show that, in the toroidal case, these ``emitted'' black holes are always small in the sense of Horowitz et al. As an application, we discuss the Grinberg-Maldacena analysis of the way one-point functions, evaluated outside an AdS-Reissner-Nordström black hole, depend on the proper time of fall from the event horizon to the Cauchy horizon. We find that, for emitted toroidal black holes, this dependence effectively drops out.
