论文摘要
我们对循环量子重力中的黑洞熵的最新情况进行了描述。本章包含一个历史摘要，并解释了如何通过依靠孤立的视野的概念来描述黑洞熵，并强调其相关对称群的不同表示。它继续审查对理解熵作为该区域的行为所必需的组合方法，并以讨论量子水平自由度的性质的讨论，这些自由度的性质解释了黑洞熵以及固定无数参数的相关问题。
We give an account of the state of the art about black hole entropy in Loop Quantum Gravity. This chapter contains a historical summary and explains how black hole entropy is described by relying on the concept of isolated horizon, with an emphasis on different representations of its associated symmetry group. It continues with a review of the combinatorial methods necessary to understand the behavior of the entropy as a function of the area and concludes with a discussion of the nature of the quantum horizon degrees of freedom that account for the black hole entropy and the related issue of the fixing of the Immirzi parameter.
