论文摘要
在这项工作中，我们研究了非线性电动力学内精确黑洞的光的弱挠度角。首先，我们使用光学时空几何形状计算高斯光学曲率。借助Gibbons和Werner普及的现代几何方式，我们检查了精确黑洞的光的偏转角。 为了这种愿望，我们确定光学高斯曲率并在光学度量上执行高斯式定理，并在弱极限近似中计算偏转角的领先术语。此外，我们同样研究了血浆培养基对精确黑洞对弱重力镜头的影响。因此，我们暴露了非线性电动力学对弱重力场偏转角的影响。
In this work, we investigate the weak deflection angle of light from exact black hole within the non-linear electrodynamics. First we calculate the Gaussian optical curvature using the optical spacetime geometry. With the help of modern geometrical way popularized by Gibbons and Werner, we examine the deflection angle of light from exact black hole. For this desire, we determine the optical Gaussian curvature and execute the Gauss-Bonnet theorem on optical metric and calculate the leading terms of deflection angle in the weak limit approximation. Furthermore, we likewise study the plasma medium's effect on weak gravitational lensing by exact black hole. Hence we expose the effect of the non-linear electrodynamics on the deflection angle in the weak gravitational field.
