| Feb 13, 2010 at 6:18 | comment | added | Bjorn Poonen | @JSE: There should be a law against texting while applying Riemann-Hurwitz. | |
| Jan 22, 2010 at 19:12 | comment | added | Anweshi | @JSE. I am unable to accept this answer because the question was in two parts, and the other part was answered by Emerton. See meta here .. tea.mathoverflow.net/discussion/178 | |

THANKS, BJORN

| Jan 10, 2010 at 6:59 | comment | added | Bjorn Poonen | @JSE: I think you meant to have 2g(X)-2 on the LHS of your Riemann-Hurwitz, in which case you need n greater than 2g+2 (the number of fixed points of the hyperelliptic involution on a hyperelliptic curve of genus g). As for algebraic space vs. scheme, it's going to be a scheme since if you include level structure what you have is quasi-projective. | |
| Jan 10, 2010 at 2:39 | comment | added | Anweshi | Thanks, this was useful. However a solution to the scheme situation also will be appreciated(perhaps from the next person). | |
