论文摘要
非平凡的差异性在通用4D黑洞的地平线上起作用，并创建了称为柔软头发的区别特征。其中包括一对左右的Virasoro代数，并带有相关的电荷，可重现Kerr黑洞的Bekenstein-Hawking熵。在本文中，我们表明，如果人们添加了负宇宙常数，则有一组类似的无限型差异性，它们在地平线上起作用。这些差异性的代数产生了中央电荷。添加边界反术，合理的以实现集成性，可导致CL = Cr的明确定义的中心电荷。 Kerr-Ads黑洞的宏观区域定律遵循的是管理黑洞微晶体的Cardy公式。
Nontrivial diffeomorphisms act on the horizon of a generic 4D black holes and create distinguishing features referred to as soft hair. Amongst these are a left-right pair of Virasoro algebras with associated charges that reproduce the Bekenstein-Hawking entropy for Kerr black holes. In this paper we show that if one adds a negative cosmological constant, there is a similar set of infinitesimal diffeomorphisms that act non-trivially on the horizon. The algebra of these diffeomorphisms gives rise to a central charge. Adding a boundary counterterm, justified to achieve integrability, leads to well-defined central charges with cL = cR. The macroscopic area law for Kerr-AdS black holes follows from the assumption of a Cardy formula governing the black hole microstates.
