Generalized Discrete Valuation Rings

Canadian Journal of Mathematics, 1969
Jategaonkar (5) has constructed a class of rings which can be used to provide counterexamples to problems concerning unique factorization in non-commutative domains, the left-right symmetry of the global dimension for a right- Noetherian ring and the transhnite powers of the Jacobson radical of a right- Noetherian ring.

Upper ramification groups for arbitrary valuation rings

Tunisian Journal of Mathematics, 2019
T. Saito established a ramification theory for ring extensions of complete intersection. We show that for a Henselian valuation ring $A$ with field of fractions $K$ and for a finite Galois extension $L$ of $K$, the integral closure $B$ of $A$ in $L$ is a

Models of curves over discrete valuation rings

Duke mathematical journal, 2018
Let C be a smooth projective curve over a discretely valued field K, defined by an affine equation f(x,y)=0. We construct a model of C over the ring of integers of K using a toroidal embedding associated to the Newton polygon of f.

Valuations and Prufer Rings

Canadian Journal of Mathematics, 1974
The word ring is used to mean commutative ring. Just as valuations on fields are used to study domains, so valuations on rings can be used to study rings; these rings need not have units [12]. We introduce slightly weaker conditions than having identity in order to get a more general theory.

On the Rings of Valuation Vectors

The Annals of Mathematics, 1953
Let {R,,,} be a system of topological rings and Qa open subrings of Ra . We consider the set R of all vectors a = (aa), where aa are elements in Ra and which belong to Qa, except for a finite number of a. By the usual definition of component-wise addition and multiplication, R forms a ring containing the direct sum 0 of all Qa .

REAL CLOSED RINGS AND ORDERED VALUATION RING

Mathematical Logic Quarterly, 1983
The article contains some model theoretic results on real closed rings and ordered valuation rings, supplementing the work of Cherlin and Dickmann on the same subject. The results confirm the analogy between real closed rings and real closed fields. There is a minor error in Proposition 1.9 which is part of Theorem 1.

A Note on Henselian Valuation Rings

Canadian Mathematical Bulletin, 1968
Let K be a field and Ka its algebraic closure. A valuation a ring A of K is called henselian, if there is only one valuation ring C of Ka which lies over A (i.e. such that C ∩ K = A) or, equivalently, if Hensel's Lemma is valid for K, A (see [5], F). In the following, we shall consider only rank one valuation rings.

Filtration on a Ring Make a Quasi Valuation or Valuation Ring

2015
In this paper we show that if R is a filtered ring then we can define a quasi valuation ring. And there exists a valuation ring if R is some kind of filtered ring. Then we prove some properties and relations between filtered ring and quasi valuation ring and valuation ...
