我们研究了一个二维的引力理论耦合到物质，这是相关的描述黑洞的全息特性与两个相等的角动量在五维（有或没有宇宙常数）。我们专注于近极端黑洞的近视界几何，其中有效的理论减少到Jackiw-Teitelboim（JT）引力耦合到一个大规模的标量场。我们计算的相关函数的修正，由于立方相互作用存在于这个理论。一个新的特点是这些修正没有明确的符号：对于AdS_55黑洞，符号取决于极值解的质量。我们从引力和全息的角度讨论了这些修正的可能解释。我们还量化了JT部门在UV区域上的印记，即这些自由度，近视界区域的特征，如何影响黑洞的渐近远区域。这提供了一个有趣的见解，如何解释红外模式的背景下，他们的紫外线完成，这取决于环境，包含黑洞。
We study a two-dimensional theory of gravity coupled to matter that is relevant to describe holographic properties of black holes with two equal angular momenta in five dimensions (with or without cosmological constant). We focus on the near-horizon geometry of the near-extremal black hole, where the effective theory reduces to Jackiw-Teitelboim (JT) gravity coupled to a massive scalar field. We compute the corrections to correlation functions due to cubic interactions present in this theory. A novel feature is that these corrections do not have a definite sign: for AdS_55 black holes the sign depends on the mass of the extremal solution. We discuss possible interpretations of these corrections from a gravitational and holographic perspective. We also quantify the imprint of the JT sector on the UV region, i.e. how these degrees of freedom, characteristic for the near-horizon region, influence the asymptotically far region of the black hole. This gives an interesting insight on how to interpret the IR modes in the context of their UV completion, which depends on the environment that contains the black hole.
