摘要

爱因斯坦四维真空方程的黑洞解只包含一个例子：克尔黑洞。在过去的二十年里，我们已经了解到高维黑洞的数量要多得多。我基于三个关键思想，直截了当地说明了这种丰富的原因：(I) \(D>4\)的视野可以很长。长远的眼光是灵活的。长远的眼光是不稳定的。最后，我对分类问题提出了一些看法和猜想。

Black holes galore in \(D>4\)

The black hole solutions to Einstein’s vacuum equations in four dimensions contain just one example: the Kerr black hole. Over the past two decades, we have understood that higher-dimensional black holes are far more plentiful. I give a straightforward account of the reasons for this abundance based on three key ideas: (i) Horizons in \(D>4\) can be long. (ii) Long horizons are flexible. (iii) Long horizons are unstable. I conclude with some comments and conjectures about the classification problem.

期刊介绍： General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
