| Feb 19, 2011 at 23:56 | comment | added | JSE | Is it right to say that SGP's p-adic log argument and Jared's Silverman-style argument and the Maulik-Poonen-Voisin argument are all, in some sense, cousins? I think all show, in some sense, that the torsion points are nowhere dense adelically. | |
| Feb 19, 2011 at 15:59 | comment | added | Ramin | Just read the blog post. Incidentally, this question came up in Davesh's colloquium talk yesterday. He and I both thought that the formal group argument that Jared suggests is a good natural way to do this, except that formal groups are not exactly elementary, and that there are no formal groups for general algebraic dynamical systems (the latter remark is due to A. Medvedev). | |
| Feb 19, 2011 at 14:39 | comment | added | JSE | I like this question! It's a good way of making the point that countable unions of closed subschemes are weird. I blogged about this and related problems: quomodocumque.wordpress.com/2008/12/15/… (note -- that post is out of date.) | |
