A new asymptotical flat and spherically symmetric solution in the generalized Einstein–Cartan–Kibble–Sciama gravity and gravitational lensing
We firstly present a new asymptotical flat and spherically symmetric solution in the generalized Einstein–Cartan–Kibble–Sciama theory of gravity and then investigate the propagation of photon in this background. This solution possesses three independent parameters which affect sharply photon sphere, deflection angle of light ray and gravitational lensing. Since the condition …
