Voting to close. It's not clear to me exactly what question you are trying to ask. (Providing a clearer reference to this article of Beauville would be helpful, for a start.) –  David Loeffler May 22 '11 at 13:24

I don't see why this question should be closed. It is only poorly presented. It would make more sense to encourage and help the person asking to improve it. I vote to keep it open. I also vote to encourage MO users to be a little more patient and compassionate towards others. –  Sándor Kovács May 22 '11 at 14:01
