21. Superconducting fluctuations enhance the conductivity, but without changing the Hall conductivity, as shown recently by Aronov A, Hikami S and Larkm A I 1995 Phys. Rev. B 51 3880 This means that the conductivity is enhanced, but the Hall angle is suppressed by superconducting fluctuations. By the f-sum and t-sum rules, this means that the decay rates of electric currents and Hall currents are reduced and enhanced respectively, by superconducting fluctuations.

38. Note that by choosing p* so that electrons and holes are degenerate to quadratic order, we will ensure that this Hamiltonian is diagonal to quadratic order. For the calculations that we describe, an explicit form for the quadratic corrections to p* is not required.

40. One might argue that a scattering rate ∼ω is in contradiction to the assumption of a well defined quasiparticle peak in the spectral function. Under these circumstances one can integrate over momentum as is done for the high-temperature electron-phonon systems to derive a similar transport equation.
