论文摘要
我们扩展了对BHS和D-BRANES沙发 - 倾斜保形反转的调查。我们分析了$ d = 4 $的渐近旋转电荷BHS，特别是在Stu Supergavity中的极端旋转BHS，并找到不变的费用。由于临界半径对冲击参数的依赖性，通过纳入边界项，通过包含在光子 - 哈洛内部的地球上的测量学角度的散射角度与地球上的地球上的刺激角度之间的关系。我们还考虑在$ d = 5 $中旋转BHS，并旋转D3-branes，并在广义的沙发倾倒倒置下找到不变性，以进行角动量的特殊选择。 las，我们找不到任何类似的对称性，用于平滑地平线的几何形状。此外，依靠经典的BH扰动理论与量子seiberg-witten曲线之间的惊人联系，以$ {\ cal n} = 2 $符号理论，我们研究了这些背景中的标量波方程，并确定了近超级BH合并中产生的近乎超级电视模式。最后，我们研究了ADS $ _4 $的Kerr-Newman BHS周围的标量波动，并为在极端情况下放松或允许重新恢复波浪函数的广义沙发倾斜对称性的严格条件。
We extend our investigation on Couch-Torrence conformal inversions of BHs and D-branes in various directions. We analyse asymptotically flat rotating charged BHs in $D=4$, in particular extremal rotating BHs in STU supergavity, and find invariance for special choices of the charges. Due to the dependence of the critical radii on the impact parameter(s), the relation between the scattering angle for geodesics outside the photon-halo and the in-spiralling angle for geodesics inside the photon-halo is modified by the inclusion of a boundary term. We also consider rotating BHs in $D=5$ and rotating D3-branes and find invariance under generalised Couch-Torrence inversions for special choices of the angular momenta. Alas we don't find any similar symmetry for smooth horizonless geometries. Moreover, relying on the surprising connection between classical BH perturbation theory and quantum Seiberg-Witten curves for ${\cal N}=2$ SYM theories, we study scalar wave equations in these backgrounds and identify the near super-radiant modes produced in near-extremal BH mergers. Finally, we study scalar fluctuations around Kerr-Newman BHs in AdS$_4$ and find stringent conditions for generalised Couch-Torrence symmetry that are relaxed in the extremal case or by allowing a rescaling of the wave function.
