论文摘要
我们开发一种形式主义，以计算在四个维度以及后者的无水平微分几何的四个维度和超对称黑洞的非超对称黑洞和超对称黑洞的矩和超对称黑洞的比率。对于超对称性和Kerr黑洞，许多这些多重矩消失了，它们的无量纲比率不明确。我们提出了两种计算这些无量纲比率的方法，对于某些超对称黑洞而言，它们非常吻合。我们还计算了Kerr解决方案的这些无量纲比率。我们的方法使我们能够计算出迄今为止迄今未知参数的无限参数，为我们提供了新的窗口。
We develop a formalism to compute the gravitational multipole moments and ratios of moments of non-extremal and of supersymmetric black holes in four dimensions, as well as of horizonless microstate geometries of the latter. For supersymmetric and for Kerr black holes many of these multipole moments vanish, and their dimensionless ratios are ill-defined. We present two methods to compute these dimensionless ratios, which for certain supersymmetric black holes agree spectacularly. We also compute these dimensionless ratios for the Kerr solution. Our methods allow us to calculate an infinite number of hitherto unknown parameters of Kerr black holes, giving us a new window into their physics.
