T. Hattori et H. Watanabe, MATHEMATICAL DERIVATION OF CHIRAL ANOMALY IN LATTICE GAUGE-THEORY WITH WILSONS ACTION, Journal of mathematical physics, 39(9), 1998, pp. 4449-4475
Chiral U(1) anomaly is derived with, mathematical rigor for a Euclidea
n fermion coupled to a smooth external U(1) gauge-field on an even dim
ensional torus as a continuum limit of lattice regularized fermion hel
d theory With the Wilson term in the action. The present work rigorous
ly proves for the Institute that the Wilson term correctly reproduces
the chiral anomaly. (C) 1998 American Institute of Physics.
