This fixed point is related to the one found in d = 2 + ϵ ϵ dimensions by perturbative methods in the sense that it is recovered in the nonperturbative approach presented here by inserting d = 2 + ϵ ϵ into the β β -functions and expanding in powers of ϵ ϵ . Since the β β -functions were shown to exist and explicitly computed for any real, i.e., not necessarily integer value of d , no analytic continuation is involved here. The fixed point in d = 4 dimensions, too, is a direct result of the nonperturbative flow equations, and, in contrast to the earlier attempts, no extrapolation in ϵ ϵ is required.
