Abstract

In this paper, we first use the optical metrics of black-bounce traversable wormholes to calculate the Gaussiancurvature. Then we use the Gauss–Bonnet theorem to obtain the weak deflection angle of light from the black-bouncetraversable wormholes. We investigate the effect of dark matter medium on weak deflection angle using the Gauss–Bonnet theorem. We show how weak deflection angle of wormhole is affected by the bounce parametera. Using theGauss–Bonnet theorem for calculating weak deflection angle shows us that light bending can be thought as a global andtopological effect.
暗物质介质中利用Gauss–Bonnet定理研究可穿越黑洞的弱偏转角
在本文中,我们首先使用黑色反弹可遍历虫洞的光学度量来计算高斯曲率。然后,我们使用高斯-博内特定理来获得来自黑色可反弹虫洞的光的弱偏转角。我们利用高斯-博内特定理研究了暗物质介质对弱偏转角的影响。我们展示了虫洞的弱偏转角如何受到反弹参数a的影响。利用高斯-博内特定理计算弱偏转角表明,光弯曲可以被认为是一种全局的拓扑效应。
