摘要：

We present analytic results on the renormalisation group flow in non-compact lattice QED with staggered fermions for large bare mass and in weak-coupling perturbation theory at non-zero lattice spacing. The large-mass expansion provides information about the flow for all values of the bare charge and, assuming a critical point at non-zero bare charge, leads to an upper bound on the renormalised charge. There is no indication of non-triviality from the large-mass results alone. © 1990.
