关于黑洞通常类似于流体块这一古老的提示性观察，最近被超越了对精确二元性的类比。我们研究了这种二元性的一些方面，特别是阐明了流体的面积最小化与黑洞视界面积最大化之间的关系，以及流体的表面张力和曲率与黑洞的表面引力之间的关系。我们还论证了流体管中的瑞利-平台不稳定性是黑弦的Gregory-Laflamme不稳定性的全息对偶。与这种流体不稳定性相关的是我们详细研究的各种流体溶液的相，尤其包括旋转的影响。我们将它们与渐近平坦黑洞的已知结果进行了比较，发现了惊人的一致。此外，我们使用我们的流体结果来讨论引力系统的未知特征。最后，我们做了一些观察，表明渐近平坦的黑洞在大维的极限下可能允许流体描述。
The old suggestive observation that black holes often resemble lumps of fluid has recently been taken beyond the level of an analogy to a precise duality. We investigate aspects of this duality, and in particular clarify the relation between area minimization of the fluid vs. area maximization of the black hole horizon, and the connection between surface tension and curvature of the fluid, and surface gravity of the black hole. We also argue that the Rayleigh-Plateau instability in a fluid tube is the holographic dual of the Gregory-Laflamme instability of a black string. Associated with this fluid instability there is a rich variety of phases of fluid solutions that we study in detail, including in particular the effects of rotation. We compare them against the known results for asymptotically flat black holes finding remarkable agreement. Furthermore, we use our fluid results to discuss the unknown features of the gravitational system. Finally, we make some observations that suggest that asymptotically flat black holes may admit a fluid description in the limit of large number of dimensions.
