我们认为，当使用适当的热力学变量集时，贝肯斯坦-霍金定律仍然适用于具有锥形奇点的渐近平坦黑色物体。然而，进入热力学第一定律的质能与阿诺维特-德斯-米斯纳质量并不一致；它与后者的不同之处在于与锥形奇点相关的能量，正如一个渐近的静态观察者所看到的那样。这些说法得到了一些例子的支持：巴赫-魏尔（双史瓦西）解，它在爱因斯坦-麦克斯韦理论中的二空穴推广和五维静态黑环。
We argue that, when working with the appropriate set of thermodynamical variables, the Bekenstein-Hawking law still holds for asymptotically flat black objects with conical singularities. The mass energy which enters the first law of thermodynamics does not, however, coincide with the Arnowitt-Deser-Misner mass; it differs from the latter by the energy associated with the conical singularity, as seen by an asymptotic, static observer. These statements are supported by a number of examples: the Bach-Weyl (double-Schwarzschild) solution, its dihole generalization in Einstein-Maxwell theory and the five-dimensional static black ring.
