Abstract
By carrying out a systematic expansion of Feynman integrals in the lat tice spacing, we show that the axial anomaly in the U(1) lattice gauge theory with Wilson fermions, as determined in one-loop order from an irrelevant lattice operator in the Ward identity, must necessarily be identical to that computed from the dimensionally regulated continuum Feynman integrals for the triangle diagrams. [S0556-2821(98)03917-4].
