WebLet be a discrete valuation ring and let be a finite -module. Then the map is surjective. Proof. Let be the torsion submodule. Then we have (holds over any domain). Hence we may assume that is torsion free. Then is free by Lemma 15.22.11 and the lemma is clear. Lemma 15.23.4. Let be a Noetherian domain.

Web9 jul. 2001 · 1.. IntroductionThe category TF R of finite rank torsion-free modules over a discrete valuation ring R with prime p is known to be complex. For instance, if S is a finite antichain, then there are uncountably many different embeddings of the category rep(S,R) of finite rank free R-representations of S into TF R [4].The complexity of TF R is …
Webdiscrete valuation ring, discrete valuation domain. A ring with a discrete valuation, i.e. an integral domain with a unit element in which there exists an element $ \pi $ such that any non-zero ideal is generated by some power of the element $ \pi $; such an element is called a uniformizing parameter, and is defined up to multiplication by an invertible element.
