论文摘要
我们研究了极端reissner-nordström黑洞的光子球附近的射线偏转角的仿射扰动系列。我们将仿射扰动系列的0和第一阶与在强挠度极限中的偏转角度进行比较。我们得出的结论是，仿射扰动系列的0阶比在强挠度限制中的挠度角度更准确，并且我们应该使用仿射扰动系列的0阶来改善强烈反射限制分析。
We investigate the affine perturbation series of the deflection angle of a ray near the photon sphere of an extreme Reissner-Nordström black hole. We compare the 0th and 1st orders of the affine perturbation series with the deflection angle in a strong deflection limit. We conclude that the 0th order of the affine perturbation series is more accurate than the deflection angle in the strong deflection limit and that we should improve a strong-deflection-limit analysis by using the 0th order of the affine perturbation series.
