Abstract :
The chiral and scale anomalies of a very general class of non local Dirac operators are computed using the ζ-function definition of the fermionic determinant. For the axial anomaly all new terms introduced by the non locality are shown to be removable by counter terms. It is verified that the non local Dirac operators have the standard minimal anomaly in Bardeenʹs form.
