comment Universal property of the Abel map
Thank you! I'd have the following question: Why did you pick $n>2g+99$ ? Wouldn't $n=g$ suffice to get $L(D+rP_0)$ nonzero ?

comment Isogenies and dimensions
Thank you! But it seems a bit involved (the hypothesis being way more general than what we need). I wonder if there is a simpler argument.

comment Isogenies and dimensions
$g=g'$, $g\ge g'$ or the linear map is surjective are equivalent, since it is injective.

comment Subtori of a complex torus
So subtori are Lie subgroups of the Lie group $X$, right ?

comment Subtori of a complex torus
In some other notes, they seem to claim that any subtorus is of the form $(V+\Lambda)/\Lambda$, where $V$ is a subspace of $\mathbb{C}^g$.
