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 $\mathbb{C}^g$.

comment Decomposition of a representation of $S_3$ on monomials
Thank you for that. Indeed, I wondered whether it is possible to give a simple explicit decomposition or not. Given these elements, it sounds like case by case work would have to be done...

comment Generic filters in the ground model (forcing)
Oh, that's right. We have $P\in\mathfrak{M}$, but the subset $\{p_n\}$ might not belong to $\mathfrak{M}$ itself. Thank you!
