Construction of the Renormalized Gross-Neveu Trajectory in 
$2-\epsilon$ Dimensions
(56K, LaTeX2e)

ABSTRACT.  We construct the renormalized Gross-Neveu trajectory in $2-\epsilon$ 
dimensions. Our construction uses a contraction mapping for an 
extended renormalization group. The extension is a running coupling 
with linear step $\beta$-function. The contraction mapping relies 
on norm estimates for a fermionic momentum space renormalization 
group.
