| Dec 3, 2013 at 0:45 | comment | added | Michael | @TomGoodwillie: what if both domain and image are simply-connected? | |
| May 4, 2011 at 0:16 | comment | added | Tom Goodwillie | No true. Take $f(z)=z^3-3z$ and restrict it to the complement of $\lbrace 1,-1\rbrace$ so that $f'(z)$ is never $0$. It maps this domain onto $\mathbb C$. | |
