The von Neumann Model and the Early Models of General Equilibrium [PDF]

, 2003
The paper reconstructs the von Neumann model, comments on its salient features and critically reviews some of its generalisations. The issues related to thetreatment of consumption, decomposability and uniqueness of the rate of growth and interest will ...

Rings Whose Pure-Projective Modules Have Maximal or Minimal Projectivity Domain

Journal of New Theory
In this study, we investigate the projectivity domain of pure-projective modules. A pure-projective module is called special-pure-projective (s-pure-projective) module if its projectivity domain contains only regular modules. First, we describe all rings

A valuation ring analogue of von Neumann regularity

Annals of Pure and Applied Logic, 2007
The author unifies results on certain (Rumely) domains, arising from the work of \textit{A.~Macintyre} and \textit{L.~van den Dries} [``The logic of Rumely's local-global principle'', J.~Reine Angew.~Math. 407, 33--56 (1990; Zbl 0703.13021)], and \textit{A.~Prestel} and \textit{J.~Schmid} [``Existentially closed domains with radical relations'', J ...

Normal Subgroups of Classical Groups over von Neumann Regular Rings [PDF]

, 1994
Let R be a von Neumann regular ring. We obtain a complete description of all subgroups of the pseudo-orthogonal groups O2nR for n ≥ 3 which are normalized by elementary orthogonal matrices.

On Weakly von Neumann regular rings

, 2009
In this paper, we define and study a particular case of von Neumann regular notion called a weak von Neumann regular ring. It shown that the polynomial ring $R[x]$ is weak von Neumann regular if and only if $R$ has exactly two idempotent elements. We provide necessary and sufficient conditions for $ R=A\propto E $ to be a weak von Neumann ring.

A Note on ϕ-Pseudo 2-Prime Ideals

Journal of Mathematics
This paper explores the concept of ϕ-pseudo 2-prime ideals within the framework of commutative rings. Let R be a commutative ring having a nonzero identity and ϕ:LR⟶LR∪∅ be a function, where LR is the lattice of all ideals of R.

Classification of Boolean algebras through von Neumann regular C∞−rings

In this paper, we introduce the concept of a “von Neumann regular C∞-ring”, which is a model for a specific equational theory. We delve into the characteristics of these rings and demonstrate that each Boolean space can be effectively represented as the ...

New characterizations of Von Neumann regular rings and a conjecture of Shamsuddin [PDF]

, 1996
A theorem of Utumi states that if R is a right self-injective ring such that every maximal ideal has nonzero annihilator, then R modulo the Jacobson radical J is a finite product of simple rings and is a Von Neuman regular ring. We prove two theorems and
