论文摘要
黑洞形成的两个主要过程是：一个，物质云自身重力下的崩溃，另一个是物质在已经存在的引力中心上积聚。这两个过程的必要条件是，折叠流体元件或测试颗粒上的总体力是有吸引力的。事实证明，通常在更高的尺寸中，事实并非如此，而对于具有非零角动量的崩溃或吸收物质大于通常的四个。因此，这两个过程都不能在较高的维度上运行以形成旋转的黑洞。在较高维度中，这种情况不是这种情况的唯一理论是纯洛夫洛克引力，这两个过程原则上都可以用于形成黑洞。
The two main processes of black hole formation are: one, collapse of a matter cloud under its own gravity and the other is accretion of matter onto an already existing gravitating centre. The necessary condition for both the processes to operate is that overall force on collapsing fluid element or on test accreting particles is attractive. It turns out that this is not the case in general in higher dimensions greater than the usual four for collapsing or accreting matter having non-zero angular momentum. Thus both these processes cannot operate in higher dimensions to form a rotating black hole. The only theory in which this is not the case in higher dimensions is the pure Lovelock gravity where both these processes could in principle work for formation of black holes.
