29. d(x - x′) correlator in Eq. (2.2), or as will be discussed below for models with exact rotational invariance, the KPZ term is forbidden for any velocity ν. If the correlations have a finite range it may not be exact, leading to a small KPZ term, estimated at finite velocity in [2].
30. A nonperturbative proof of this was recently obtained from the exact solution at large N [28].
31. The equivalence of the combinatorial factors for δλ. and δc can be deduced by imagining Δ to be two independent vertices of the statics and observing that both diagrams correct the same vertex after using FDT.
