We remind (see e.g. =-=[14]-=-) that an interaction is stable if it fulfills the following condition: U(q1, · · · , qj) = ∑ i<h Φ(|qi − qh|) ≥ −Bj (8.1) for some constant B > 0 .

Actually it is clear that, in the BG limit, this term is the only O(1) term in the sum in the right hand side of (3.16). Indeed, for m > 0 and fixed j, the size of Aεj+1+m will be O(Nm+1ε2ε3m) , (3.... |
