\(P\)-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] .
