Ward identities and the physical interpretations of anomalies in stochastic quantization
The Ward identities are obtained for vector and axial currents through a functional integral representation of the Langvin equations for the stochastic quantization of fermions in an external gauge field. In this approach anomalies appear as due to fluctuations in the evolution of the system to its...
