Single Scale Analysis of Many Fermion Systems. Part 2: The First Scale
The first renormalization group map arising from the momentum space

differs from all subsequent maps. Namely, the component of momentum dual to
temperature may be arbitrarily large - there is no ultraviolet cutoff. The
methods of Part 1 are supplemented to control this special case.Comment: 45 page
