Abstract

We show how both the vector-current conservation and the axial-vector current anomaly follow directly from the Langevin equations of motion for spinor field theories in the stochastic quantization formalism. Our method employs Novikov's theorem for Grassmann variables and the regularization procedure of Bern, Chan and Halpern.
