在这篇文章中，我们回顾了黑褶的方法，最近开发的有效的世界体积描述的高维黑洞，捕获的长波长动态的黑洞的视界表现出两个特征长度的大小非常不同。在这种情况下，黑洞被认为是弯曲到背景时空的子流形中的黑膜，并且可以用生活在动力学世界体积上的有效流体来表述。我们讨论了由此产生的Blackfold方程，它分为一组内在和外在的方程。给出了稳态位形内禀流体方程的一般解，沿着给出了一类新的稳态黑洞解。我们还评论了如何可以使用的形式主义来研究时间演化和稳定性的黑褶皱。
In this article we review the blackfold approach, a recently developed effective worldvolume description of higher-dimensional black holes, that captures the long wavelength dynamics of black holes with horizons exhibiting two characteristic lengths of very different size. In this regime the black hole is regarded as a black brane curved into a submanifold of a background spacetime, and can be formulated in terms of an effective fluid that lives on a dynamical worldvolume. We discuss the resulting blackfold equations, which separate into a set of intrinsic and extrinsic equations. The general solution of the intrinsic fluid equations for stationary configurations is presented along with a class of novel stationary black hole solutions. We also comment on how the formalism can be used to study time evolution and stability of blackfolds.
