Jul 26, 2014 at 6:35 | comment | added | Mikhail Bondarko | This is probably true. Yet do you now any references for this (where some terms are introduced)? | |
Jul 25, 2014 at 21:31 | comment | added | Will Sawin | I believe one wants to consider models of $F$ of finite type only. Then one needs $A$ to be a localization of a finitely generated subring of itself - this is clearly a necessary and sufficient condition. I don't know a better one. | |
Jul 25, 2014 at 20:01 | comment | added | Mikhail Bondarko | Possibly I am getting something wrong; yet in the 'geometrical' case there are 'bad' valuations; see mathoverflow.net/questions/135544/… | |
Jul 25, 2014 at 15:53 | comment | added | Daniel Loughran | Perhaps I am misunderstanding your question, but don't all discrete valuations on $F$ arise this way? Namely, given a discrete valuation $v$ on $F$, one can consider the associated discrete valuation ring $A \subset F$. Then $\mbox{Spec } A$ is a model for $F$, whose point of codimension $1$ gives rise to the required discrete valuation $v$. | |
