| Nov 22, 2023 at 20:46 | comment | added | jg1896 | @DonuArapura $\mathbb{D}(X)$ has many maximal comutative subfields, and given knowledge of $\mathbb{D}(X)$ only, there is no way to recover the particular subfield $k(X)$. For instance $\mathbb{D}(\mathbb{A}^1)$ have subfields of the the form $k(C)$, where $C$ is a curve of arbitrary genus. | |
| Nov 22, 2023 at 18:13 | comment | added | Donu Arapura | I assume that the usual function field $K(X)$ would be embedded into $\mathbb{D}(X)$. Would it be a maximal commutative subfield? If so, then you should be answer Q1. | |
