| Abstract: | We verify that quadratic divergences stemming from gravitational corrections to quantum electrodynamics (QED) which have been conjectured to lead to asymptotic freedom near Planck scale are arbitrary (regularization dependent) and compatible with zero. Moreover, we explicitly show that such arbitrary term contributes to the beta function of QED in a gauge dependent way in the gravitational sector. |
