Gauge fixing, BRS invariance and Ward identities for randomly stirred flows
Arjun Berera, David Hochberg
The Galilean invariance of the Navier-Stokes equation is shown to be akin to a global gauge symmetry familiar from quantum field theory. This symmetry leads to a multiple counting…

Gauge symmetry and Slavnov-Taylor identities for randomly stirred fluids
A. Berera, D. Hochberg
The path integral for randomly forced incompressible fluids is shown to have an underlying Becchi-Rouet-Stora (BRS) symmetry as a consequence of Galilean invariance. This symmetry…
