多重轴对称黑洞的angular momentum-质量不等式的数值证据

Numerical evidences for the angular momentum-mass inequality for multiple axially symmetric black holes

Sergio Dain, Omar Ortiz

摘要:

我们给出了多个轴对称(非稳态)黑洞的总质量和总角动量不等式的有效性的数值证据。我们使用抛物热流数值求解定常轴对称爱因斯坦方程。作为我们的方法的副产品,我们也给出了数值证据,有没有正规的爱因斯坦方程描述两个极端,轴对称黑洞平衡的解决方案。

英文摘要:

We present numerical evidences for the validity of the inequality between the total mass and the total angular momentum for multiple axially symmetric (non-stationary) black holes. We use a parabolic heat flow to solve numerically the stationary axially symmetric Einstein equations. As a by product our method, we also give numerical evidences that there are no regular solutions of Einstein equations that describe two extreme, axially symmetric black holes in equilibrium.
