Photon trajectories on a first order scale-dependent static BTZ black hole

In this paper we study the motion of massless particles on a static Baados-Teitelboim-Zanelli black hole background in the context of scale-dependent gravity, which is characterized by the running parameter. Thus, by using standard methods we obtain the equation of motions and then analytic solutions are found. The relevant non-trivial differences appear when we compare our solution against the classical counterpart.
