| Jan 7, 2016 at 16:56 | comment | added | YCor | Note that that the complex case is essentially obvious, the real case is really subtle. Also here components have to be understood in the real topology (for instance, $\mathrm{PGL}_2(\mathbf{R})=\mathrm{Aut}(\mathfrak{sl}_2(\mathbf{R}))$ has 1 Zariski component but two real components). | |
