| Jan 26, 2010 at 20:54 | comment | added | Anweshi | @Dror. It is a matter of background and training. I learnt a bit of number theory and algebraic geometry, but nothing from Lie groups/Lie Algebras. So I find "etale" more comfortable than "formal groups". If I knew anything from Lie groups, I might have preferred formal groups. Problem is, I don't yet fully understand what is the deal with them. | |
| Jan 10, 2010 at 21:38 | comment | added | Dror Speiser | Personally, I find formal groups much easier to understand than anything with the word etale in it. Though, while I am sure I am not the only one with this opinion, I am also quite sure this is uncalled for and self destructive... | |
| Jan 5, 2010 at 15:12 | comment | added | Anweshi | I still prefer this answer, as it looks more "arithmetical" and I need to understand one thing less for figuring this out. Sorry if this erodes your opinion of me. | |

| Jan 5, 2010 at 11:56 | comment | added | Pete L. Clark | Both answers are correct, and two correct answers should be enough: I don't think that if you wait longer you'll get an obviously superior answer. Go ahead and choose whichever one seems best to you. (I upvoted Felipe's answer, if that influences your decision at all.) | |
| Jan 5, 2010 at 11:33 | comment | added | Anweshi | MO is asking me to choose an answer. I myself do not know which is the best one; however I am leaning towards this one as it is not using formal groups. If someone more learned would give suggestions, my job would be easier. Or maybe I should wait for longer time? | |
