Question about specifying complex 1-motives
Hmm... I'm an algebraic geometer, so I don't know that much complex geometry. Why is that extension analytic again? A lot of the 1-motive he defines directly from the divisor groups. |

If $k[S]$ is noetherian, is S finitely generated?
Right. So then can we make an increasing chain of ideals by picking $s_1 \in S$, setting $I_1 = (s_1)$, and then by induction picking $s_{k+1} \in $S\backslash\I_k$ and setting $I_{k+1} = I_k + (s_{k+1})$? This chain eventually terminates, which I think means that $S$ is finitely generated? |

If $k[S]$ is noetherian, is S finitely generated?
Oh, I see now. I guess I'm taking $k[t]$ and then finding a sub-semigroup inside there, instead of taking a semigroup $S$ and then making $k[S]$. |

If $k[S]$ is noetherian, is S finitely generated?
Sorry, I guess I mean the semigroup generated by the $t/a^n$. I've edited my post to reflect this change. And I'm missing something, but I don't quite understand what you mean by the elements of $S$ are by definition linearly independent? |

Expressions for the Square of an Integral
If $I$ is the value of the integral, why can't you just take $s(x) = I^2/(Au(x))$? This is probably not the answer you were looking for, so can you be more specific? |

Finding the codomain of a monoid homomorphism
Whoops! I thought that "monoid homomorphism" in the title referred to the function $f$ instead of the map $M \rightarrow G$. |
