Anyway, I will look at the citation you mentioned -- I mainly care about the positive characteristic case. | |

| Apr 26, 2011 at 12:11 | comment | added | Fernando Muro | Damien, the structure is not unique. Perhapes you are mislead by the fact that it is essentially unique, but there are tons precisely because of that. | |
