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.
