Ok, I have a question about this Fade'ev Popov procedure of teasing out the ghosts when one quantizes a non-Abelian gauge theory with path integrals.
The factor of 1 that people insert, for some gauge fixing function f, and some non-Abelian symmetry \mathcal{G} is:
1=\int \mathcal{D}U \delta[f(\mathbf{A})] \Delta[\mathbf{A}],
where
\mathcal{D}U = \Pi d\theta,
and
U \in \mathcal{G}.
This is probably a stupid question, but the function \Delta works out just to be a Jacobian of some sort over the manifold \mathcal{G}, right?
\Delta[\mathbf{A}] = det \left(\frac{\delta f}{\delta \theta}\right)
I am confused because no one actually says this. Am I completely off base?
Thanks in advance for helping me, and tolerating a (possibly) stupid question!
