关于带荷Riemannian Penrose不等式和宇宙监督猜想

On the Riemannian Penrose inequality with charge and the cosmic censorship conjecture

Marcus A Khuri, Sumio Yamada, Gilbert Weinstein

摘要:

我们注意到一个面积电荷不等式最初是由于吉本斯:如果最外层的地平线$S$在一个渐近平坦的电真空初始数据集是连接的,那么$|q|\leq r$,其中$q$是总电荷和$r=\sqrt{A/4π}$是面积半径的$S$。这个不等式的一个结果是,对于连通的黑洞,下面的面积下界成立:$r\geq m-\sqrt{m^2-q^2}$。结合上界$r\leq m + \sqrt{m^2-q^2}$,这意味着黎曼彭罗斯不等式的自然推广:$m\geq 1/2(r+q^2/r)$。

英文摘要:

We note an area-charge inequality orignially due to Gibbons: if the outermost horizon $S$ in an asymptotically flat electrovacuum initial data set is connected then $|q|\leq r$, where $q$ is the total charge and $r=\sqrt{A/4π}$ is the area radius of $S$. A consequence of this inequality is that for connected black holes the following lower bound on the area holds: $r\geq m-\sqrt{m^2-q^2}$. In conjunction with the upper bound $r\leq m + \sqrt{m^2-q^2}$ which is expected to hold always, this implies the natural generalization of the Riemannian Penrose inequality: $m\geq 1/2(r+q^2/r)$.
