Light bending in F[g(□)R] extended gravity theories
We show that in the weak field limit the light deflection alone cannot distinguish between different R+F[g(□)R] models of gravity, where F and g are arbitrary functions. This does not imply, however, that in all these theories an observer will see the same deflection angle. Owed to the need to calib...
