球对称引力坍缩到Schwarzschild黑洞的曲率爆破率

Curvature blow-up rates in spherically symmetric gravitational collapse to a Schwarzschild black hole

Xinliang An, Dejan Gajic

摘要:

我们研究了球对称Einstein-标量场背景下引力坍缩产生的时空黑洞内部,并研究了类空奇点在类时无穷远处的曲率和质量的精确爆破率.我们特别表明,Kretschmann标量爆炸速度比在史瓦西设置,由于质量膨胀。此外,爆破率不是常数,收敛到史瓦西率向类时无穷大,它取决于精确的后期时间多项式行为的标量场沿事件视界。这表明一种新的爆破现象,由PDE机制驱动,而不是ODE机制。

英文摘要:

We study the black hole interiors of spacetimes arising from gravitational collapse in the spherically symmetric Einstein-scalar field setting, and we investigate the precise blow-up rates of curvature and mass at the spacelike singularity near timelike infinity. We show in particular that the Kretschmann scalar blows up faster than in the Schwarzschild setting, due to mass inflation. Moreover, the blow-up rate is not constant and converges to the Schwarzschild rate towards timelike infinity and it depends on the precise late-time polynomial behaviour of the scalar field along the event horizon. This indicates a new blow-up phenomenon, driven by a PDE mechanism, rather than an ODE mechanism.
