The Core of a Module over a Two-Dimensional Regular Local Ring

open access: yesJournal of Algebra, 1997
This paper explicitly determines the core of a torsion-free, integrally closed module over a two-dimensional regular local ring. It is analogous to a result of Huneke and Swanson which determines the core of an integrally closed ideal.

Semi‐regular local rings

Mathematika, 1956
In the following pages there will be found an account of the properties of a certain class of local rings which are here termed semi-regular local rings . As this name will suggest, these rings share many properties in common with the more familiar regular local rings, but they form a larger class and the characteristic properties are preserved under ...

Erratum to "Regular Overrings of Regular Local Rings"

Transactions of the American Mathematical Society, 1975
THEOREM. Let (R, M) be an n-dimensional regular local ring, n > 1. Let x, xl, .. , xi be an R-sequence and T = R [xl/x, . . . , xi/x]. Then T is an ndimensional regular domain if and only if one of the following holds: (a) the elements x, x, ... , xi form a subset of a minimal basis for M, (b) (1) x E M2 and the elements xl, ...

\(P\)-regular and \(P\)-local rings

2021
Summary: This paper is a continuation of study rings relative to right ideal, where we study the concepts of regular and local rings relative to right ideal. We give some relations between \(P\)-local (\(P\)-regular) and local (regular) rings. New characterization obtained include necessary and sufficient conditions of a ring \(R\) to be regular, local

Regular Local Rings

2010
As mentioned before, local rings serve for the study of the local behavior of a global object, such as an affine variety. In particular, notions of local “niceness” can be defined as properties of local rings. There is a range of much-studied properties of local rings.

Wedderburn’s theorem for regular local rings

2015
Let \(R\) be a regular local ring containing a field of characteristic zero, \(K\) its field of fractions and \((V, \Phi)\) a quadratic space over \(R\). \textit{I. Panin} proved that if \((V, \Phi) \otimes_RK\) is isotropic over \(K\), then \((V, \Phi)\) is isotropic over \(R\) [Invent. Math. 176, No. 2, 397--403 (2009; Zbl 1173.11025)].

Cofiniteness of Local Cohomology Modules Over Regular Local Rings

Bulletin of the London Mathematical Society, 2000
Let \(R\) be a regular local ring of Krull dimension \(d\), \(I\) a 1-dimensional ideal of it and \(M\) a finitely generated \(R\)-module. In this paper we give a new proof of the fact that the local cohomology modules \(H^i_I(M)\) are \(I\)-cofinite, that is, \(\text{Ext}^i_R(R/I, H^i_I(M))\) are finitely generated for all \(i,j\geq 0\).

On Locally Ιnvo-Regular Ring

Advances in Nonlinear Variational Inequalities
An associative ring with identity D claimed to be locally Invo- regular ( L.Ι.Reg.Rings) if , for any element ӻ in D , either ӻ  or 1- ӻ is Invo-regular in D , that is  ӻ = ӻ v ӻ  or  1- ӻ = (1- ӻ) v (1- ӻ) for some involution element v in D , these rings due to Danchev [5] .
