论文摘要
我们介绍了（2+1）尺寸重力的旋转BTZ黑洞周围的重力镜头的详细研究。对本BH时空周围的无质量测试粒子的轨道进行研究，以描述较低维度的宇宙常数的性质。鉴于其他关键参数，我们研究宇宙常数对光子轨道的影响。鉴于宇宙学常数的不同值，用于测试颗粒的直接和逆行运动，研究了光的弯曲角。可以观察到，弯曲角略微降低，因为负区域的宇宙常数值增加。
We present a detailed study of gravitational lensing around a rotating BTZ black hole in (2+1) dimensional gravity. The study of orbits for massless test particle around this BH spacetime is performed to describe the nature of cosmological constant in lower dimensions. We study the effect of cosmological constant on the photon orbit in view of other critical parameters. The bending angle of light is studied in view of different values of cosmological constant for direct and retrograde motion of test particles. It is being observed that the bending angle slightly decreases as the value of cosmological constant increases in the negative region.
