  "abstract": "We formulate the Hartree-Fock method in large-N approximation using a functional integral approach. We then derive an exact renormalization group equation for the effective action. We organize the QED corrections into higher and low energy parts. The former is calculated by many authors. To find the latter we perform a low energy decomposition of the nuclear charge and electron mass. The renormalization group equation yields a system of ODEs for coefficients of the expansion.",
