comment Why are torsion points dense in an abelian variety?
If p>0, and assuming A ordinary, then the p-power torsion points of A(k) should also be Zariski dense in A, if I'm right.

comment Duality for rank one modules over a number ring
@Marguaux: I decided to ask on MO the original question I had, which motivates the one asked here. Here is the link: mathoverflow.net/questions/141340/…

comment Duality for rank one modules over a number ring
Thanks for the nice answer and for giving my question some more appropriate context (I got the question from looking at subgroups of ordinary abelian varieties over a finite field. In the situation I had in mind R is Z[\pi], where \pi is an ordinary Weil-number).

comment Convergence at the radius of convergence
@Neil: I see, thanks.

comment Convergence at the radius of convergence
Wouldn't uniform convergence on your disk imply that your function admits its derivative at the branch point? (By a "switch-sum-and-differentiation"-type argument.. Or am I wrong?)
