| Mar 18, 2010 at 21:48 | comment | added | JBorger | Again, are you talking about when $v$ divides $\ell$ or when it doesn't? They're completely different. In the first case, Emerton gave an answer above. In the second case, it happens if the variety has a smooth proper model over $v$, by the proper base change theorem. | |
