| contents | We show that even $ζ$-functions may be removed from the $β$-functions of general multi-coupling theories up to high loop order by means of coupling redefinitions. For theories whose $β$-function is determined by the anomalous dimensions of the fields, such as supersymmetric theories, this corresponds to a renormalisation scheme change to a momentum subtraction scheme. |
