摘要：
In this paper, we investigate the deflection angle and the trajectories of the light rays near black holes in M-theory scenarios. Using the Gauss-Bonnet theorem, we first discuss the deflection angle of the light rays near four- and seven-dimensional AdS black holes derived from the M-theory compactifications on the real spheres on S-7 and S-4, respectively. Then, we examine brane number effect and the rotating parameter on such light behaviors. We finish this work by providing a study of the light ray trajectories via the equations of motion associated with M2 and M5-branes.
