Combining Local and Von Neumann Regular Rings

open access: yesCommunications in Algebra, 2004
All rings R considered are commutative and have an identity element. Contessa called R a VNL-ring if a or 1 - a has a Von Neumann inverse whenever a ∈ R. Sample results: Every prime ideal of a VNL-ring is contained in a unique maximal 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
