| Jul 4, 2013 at 12:49 | comment | added | johndoe | Oh I see, I misinterpreted the paper. They indeed mean $K$ in $P$ as you did. | |
| Jul 4, 2013 at 12:43 | comment | added | Ben McKay | Oops, I thought $K$ was a compact subset of $P$. If $K$ is a compact subset of $X$, then of course there are lots of compactly supported gauge transformations. Take $P \to X$ trivial, and just make lots of compactly supported maps to $G$. So there are compactly supported gauge transformations, not the identity, precisely when the identity component of $G$ is not compact. | |
