摘要：

The triangle graphs with vector and axial vector couplings are investigated in the causal approach to massless QED. Since this approach does not require ultraviolet regularization the question of axial current conservation can be unambiguously discussed. Moreover, the case of massless fermions causes no serious problem. The anomaly appears in the process of distribution splitting.
