摘要：

We examine the lattice-chiral-fermion scheme proposed by Aoki, Funakubo, and Kashiwa (AFK) in the context of chiral QED in two and four dimensions. In four dimensions, we find that, although the AFK scheme ensures gauge invariance by rendering amplitudes transverse, it does not improve their ultraviolet behavior; as in the Wilson theory, the effective vacuum polarization is quadratically divergent. In both two and four dimensions, we find that there are contributions to the effective gauge-field action beyond those analyzed by AFK. These contributions are not accessible through finite-order perturbation theory. © 1990 The American Physical Society.
