    "abstract": "The application of the exact renormalisation group to a many-fermion system\nwith a short-range attractive force is studied. We assume a simple ansatz for\nthe effective action with effective bosons, describing pairing effects and\nderive a set of approximate flow equations for the effective coupling including\nboson and fermionic fluctuations.\n  The phase transition to a phase with broken symmetry is found at a critical\nvalue of the running scale. The mean-field results are recovered if boson-loop\neffects are omitted. The calculations with two different forms of the regulator\nwas shown to lead to similar results.",
