| Mar 30, 2011 at 21:01 | comment | added | José Figueroa-O'Farrill | ... and it's a group homomorphism because the Lie algebra is abelian. | |
| Mar 30, 2011 at 21:00 | comment | added | Mohan Ramachandran | @Daniel Litt:In this case the image of the exponential map is an open subroup of G and G is connected therefore it is onto. | |
| Mar 30, 2011 at 20:35 | comment | added | Daniel Litt | Why is the exponential surjective/a group homomorphism? | |
| Mar 30, 2011 at 20:34 | comment | added | Simon Rose | That's a much better answer than mine. | |
