Abstract: Anomalies and BRST invariance are governed, in the context of Lagrangian Batalin-Vilkovisky quantisation, by the master equation, whose classical limit is (S,S) = 0. Using Zimmerman's normal products and the BPHZ renormalisation method, we obtain a corresponding local quantum operator equation, which is valid to all orders in perturbation theory. The formulation implies a calculational method for anomalies that is useful also outside this context and that remains completely within regularised perturbation theory. It makes no difference in principle whether the anomaly appears at one loop or at higher loops, The method is illustrated by computing the one and two-loop anomalies in chiral W-3 gravity.
