Giuga-Agoh redux

June 9, 2011

Some years ago I mentionned that conjecture, but didn’t really make any progress then.  Recently, I’ve tried again and found what could be a simple proof, which I’ve put here.

There may still be a silly mistake somewhere, but at least that seems to be going in the right direction. Comments welcome…

UPDATE (9 june 2011): well, it was blatantly wrong indeed…  The paper has now been retracted, with apologies for the waste of time.
