极端黑洞的视界不稳定性

Horizon Instability of Extremal Black Holes

Stefanos Aretakis

摘要:

我们证明了轴对称极值视界在线性标量扰动下是不稳定的。具体来说,我们表明,平移不变的衍生物的波动方程的一般解决方案不衰减沿这样的视野先进的时间趋于无穷大,事实上,高阶衍生物爆炸。这一结果特别适用于极端的Kerr-Newman和Majumdar-Papapetrou时空,并且与次极端情况形成鲜明对比,在次极端情况下,沿着事件视界的所有导数都有衰变。

英文摘要:

We show that axisymmetric extremal horizons are unstable under linear scalar perturbations. Specifically, we show that translation invariant derivatives of generic solutions to the wave equation do not decay along such horizons as advanced time tends to infinity, and in fact, higher order derivatives blow up. This result holds in particular for extremal Kerr-Newman and Majumdar-Papapetrou spacetimes and is in stark contrast with the subextremal case for which decay is known for all derivatives along the event horizon.
