| Jan 3, 2019 at 6:26 | comment | added | mme | @Bullet51 A further argument is necessary in dimension 2. One gets that the map is weakly conformal and should argue that the set of regular points is connected to see that it is holomorphic (or antiholomorphic), and then that there are no critical points. But it remains true. | |

| Jan 3, 2019 at 6:07 | comment | added | LeechLattice | If the map is smooth, the only transformations are Möbius transformations, which follows from the Liouville's theorem on conformal mappings. | |
