| Mar 22, 2018 at 9:05 | comment | added | Jason Starr | Effectively you can choose $V_1$ to be a particular (absolutely / geometrically) irreducible variety $W$. This is equivalent to running through the proof with the field $K$ replaced by the regular extension field $K(W)$. For your second question, I completely agree that this is not obvious. The construction that I know for $K_1$ uses Zorn's lemma for the partially ordered set of chains of regular field extensions, but they need not be extensions of the form $\prod_{\alpha<\beta} F_\alpha \to \prod_{\alpha \leq \beta} F_\alpha$. | |
