    • As the collision integral generally takes a finite value in the lattice system at finite temperature, the resulting Boltzmann equation breaks time reversal symmetry, despite the fact that we started with a microscopic model which has the symmetry. This is understood by noting (i) the system of electrons on a lattice is not closed in the presence of the Umklapp processes and (ii) we chose to use the retarded Green's functions on physical grounds of causality.

    • 20) In the three dimensional case of §4.3, the parameter F will be reduced somewhat upon improving the approximation. Still it is bounded from below by the results of §4.2, i.e., F ≳ 10. On the other hand, the latter being non-zero is not invalidated, since it is solely due to 'Umklapp' processes as noted in the text. Thus, qualitatively, the objection against eq. (4.4) need not be taken seriously in our models. To investigate the validity of the approximation, a numerical work will be presented in a subsequent paper.

    • note
    • As 'Fermi liquid instabilities', we refer only those instabilities which are induced when macroscopic collective oscillations of the Fermi surface becomes unstable. The instability of microscopic origin, such as the spin-density wave instability caused by nesting of the Fermi surface, does not fall into this category.
