comment From an eigenfom with $\mathbf{Q}$-coefficients to $j$-invariants
I think the question is there. I agree that's somewhat vague. I will soon retire it.

comment From an eigenfom with $\mathbf{Q}$-coefficients to $j$-invariants
Thank you all for your answers. I guess what I had in mind was a characterization of $J_f$ starting from $f$, and not necessarily a concrete procedure to calculate $J_f$.

comment A good reference for uniformization theorem for compact and non-compact Riemann surface
Did you try Markushevich, Theory of functions of a complex variable? There you can find a proof of the theorem that any open simply connected subset of $P^1(C)$ whose complement has at least two points is biholomorphic to the disc (at least the proof was there in the italian version).

comment Is the unit tangent bundle of $S^{n}$ parallelizable?
I thought the tangent bundle $TS^n$ is parallelizable if and only if $n\in\{1;3;7\}$. For $n$ even you won't even find a nowhere vanishing vector field on $S^n$!

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).
