Valuation rings of dimension one as limits of smooth algebras

Commutative Algebra 2025-02-27 v5 Algebraic Geometry

Abstract

As in Zariski's Uniformization Theorem we show that a valuation ring VV of characteristic p>0p>0 of dimension one is a filtered direct limit of smooth Fp{\bf F}_p-algebras under some conditions of transcendence degree. Under mild conditions, the algebraic immediate extensions of valuation rings are dense if they are filtered direct limit of smooth morphisms.
