| Mar 24, 2012 at 20:33 | comment | added | Misha | @Guntram: You are right of course, but if you eliminate the (uncountable) Axiom of Choice, then, at least in Solovay's model, all subsets of ${\mathbb R}$ are measurable and we are in the situation discussed in mathoverflow.net/questions/64116/… (see pm's answer). | |
| Mar 24, 2012 at 10:00 | comment | added | Guntram | For the existence of wild automorphisms of $\mathbf{C}$ and for the construction Misha quoted (due to Borel--Tits) you need the axiom of choice, however. | |

| Mar 23, 2012 at 12:37 | comment | added | YCor | You can embed $SL_2(\mathbf{R})$ into $SL_2(\mathbf{C})$ and twist by a wild automorphism of $\mathbf{C}$. | |
