Divergence Anomaly and Schwinger Terms: Towards a Consistent Theory of Anomalous Classical Fluid
Arpan Krishna Mitra, Subir Ghosh
Anomaly, a generic feature of relativistic quantum field theory, is shown to be present in non-relativistic classical ideal fluid. A new result is the presence of anomalous terms i…
