8. We ignore the renormalization of the dispersion by the multiple scattering process. Alternatively one may think that we assume the effect is only to change the bare mass into the effective mass.
9. We assume that the area of the system is unity.
10. Without a cutoff, eqs. (2.6) and (2.12) logarithmically diverge in 2D.
11. F = 1), because the temperature dependence is exponentially small at low temperatures.

21. For interaction with hard core repulsion or long-range interaction, Π(q; k, k′) may not be finite. Taking summation of approproate higher order contributions, however, we can make Π(q; k, k′) finite.
