Eqs. (23) are dimensionally inconsistent: [FORMULA] must be replaced everywhere in these equations (except in the equation for [FORMULA] itself) by [FORMULA]. The magnitude V which appears in these equations is defined in the lines just above the set of Eqs. (24). In these definitions there is also a typo: when defining [FORMULA], the exponent of [FORMULA] must read [FORMULA]. In conclusion, Eqs. (24) remain the same, but Eqs. (23) now read:

[EQUATION]

In order to enable the reader the reconstruction of the RG flow, we append Table 1 with the eigenvalues of the linearized RG-equations at each fixed point. We also add the following remark: the fixed point P1 is degenerated, because in terms of dimensional couplings it corresponds to three possible cases. One always has [FORMULA], [FORMULA] (implying [FORMULA]) and one of the following three possibilities:

  • [FORMULA]: this yields [FORMULA], which is the quoted value for P1 in Table 1.

  • [FORMULA]: this yields [FORMULA].

  • [FORMULA]: this yields again [FORMULA], but this fixed point only exists if the constraint [FORMULA] is satisfied.
