论文摘要
使用高斯河网定理，我们通过旋转宇宙常数的常规黑洞来计算并检查光射线的挠度角。在光学几何形状的帮助下，我们首先处理宇宙学贡献的海沃德黑洞。然后，我们重新考虑对Bardeen解决方案的研究。我们检查宇宙学对光线挠度的恒定效应。具体而言，我们发现额外的宇宙学校正术语概括了某些获得的发现。使用图形分析，我们就KERR解决方案提供了比较讨论。结果证实，非线性电动力电荷通过通过这种宇宙黑洞降低光射线的偏转角来影响时空几何。
Using the Gauss-Bonnet theorem, we compute and examine the deflection angle of light rays by rotating regular black holes with a cosmological constant. By the help of optical geometries, we first deal with the Hayward black holes with cosmological contributions. Then, we reconsider the study of the Bardeen solutions. We inspect the cosmological constant effect on the deflection angle of light rays. Concretely, we find extra cosmological correction terms generalizing certain obtained findings. Using graphical analysis, we provide a comparative discussion with respect to the Kerr solutions. The results confirm that the non-linear electrodynamic charges affect the space-time geometry by decreasing the deflection angle of light rays by such cosmological black holes.
