    • Λ (K) is the self-energy with infrared cutoff Λ and Σ(0, i0) is the exact self-energy at vanishing momentum and frequency. At the critical point μ=Σ(0, i0), so that neither μ nor Σ(0, i0) explicitly appear in our flow equations. The counterterm Σ(0, i0) can be reconstructed from the flow of the marginal and relevant couplings [10], see also S. Ledowski and P. Kopietz, J. Phys.: Condens. Matter 15, 4779 (2003).
