论文摘要
我们在五个时空维度上复制并扩展了雷纳（Lehner）和比勒托里（Pretorius）的先前研究。我们考虑了固定厚度和不同长度的不稳定的黑色弦，在所有情况下，我们确认在进化的中间阶段，地平线可以解释为在不同尺度上连接球形黑色孔的黑弦的绝对类似序列。但是，我们找不到有关随后几代有关的全球时间尺度的任何证据。不稳定性的终点是在有限的渐近时间中从地平线上捏下来，从而证实了违反黑色弦空间周围弱宇宙审查的猜想。
We reproduce and extend the previous studies of Lehner and Pretorius of the endpoint of the Gregory-Laflamme instability of black strings in five space-time dimensions. We consider unstable black strings of fixed thickness and different lengths, and in all cases we confirm that at the intermediate stages of the evolution the horizon can be interpreted as a quasistationary self-similar sequence of black strings connecting spherical black holes on different scales. However, we do not find any evidence for a global timescale relating subsequent generations. The endpoint of the instability is the pinch off of the horizon in finite asymptotic time, thus confirming the violation of the weak cosmic censorship conjecture around black string spacetimes.
