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 ...

From regular modules to von Neumann regular rings via coordinatization
Romanian Journal of Mathematics and Computer Science, 2013 In this paper we establish a very close link (in terms of von Neumann's coordinatization) between regular modules introduced by Zelmanowitz, on one hand, and von Neumann regular rings, on the other hand: we prove that the lattice $\mathcal{L}^{fg}(M)$ of all finitely generated submodules of a finitely generated regular module $M$, over an arbitrary ...

A study of non-commutative Von-Neumann regular rings
, 2021 In this paper, we study the Von-Neumann regular elements of non-commutative rings M-2(Z(2)) and M-2(Z(3)). We prove that M-2(Z(2)) and M-3(Z(3)) are Von-Neumann rings. We also give code in C++ to compute Von-Neumann regular elements of M-2(Z(n))

Hilbert von Neumann Modules versus Concrete von Neumann Modules [PDF]
, 2022 Apart from presenting some new insights and results, one of our main purposes is to put some records in the development of von Neumann modules straight.

Von Neumann Regular McCoy Rings [PDF]
, 2021 A ring R is said to be right McCoy, if for every f(x),g(x) in the polynomial ring R[x], with f(x)g(x)=0 there exists a nonzero element cϵR with f(x)c=0. In this note, we show that von Neumann regular McCoy rings are abelian. This gives a positive

On the geometry of von Neumann algebra preduals [PDF]
, 2014 Let M be a von Neumann algebra and let M⋆ be its (unique) predual. We study when for every φ∈M⋆ there exists ψ∈M⋆ solving the equation ∥φ±ψ∥=∥φ∥=∥ψ∥. This is the case when M does not contain type I nor type III1 factors as direct summands and it is false

关于右GP-V-环(On right GP-V-rings)
Zhejiang Daxue xuebao. Lixue ban, 2009 GP-V-ring(GP-V-module) is studied which is a generalization of P-V-ring (P-V-module), and the characters are searched for. For example,if R is a right GP-V-ring, then for any maximal subideal K of a principal right ideal U= aR, a ∈R, there exists a ...

On spectral compactness of von neumann regular rings [PDF]
, 2012 We characterize the spectral compactness of commutative von Neumann regular rings. We show that through a process of adjunction of identity, we can obtain the Alexandroff compactification or a star compactification of the prime spectrum of certain von ...

Characterizing $S$-flat modules and $S$-von Neumann regular rings by uniformity
, 2021 Let $R$ be a ring and $S$ a multiplicative subset of $R$. An $R$-module $T$ is called $u$-$S$-torsion ($u$- always abbreviates uniformly) provided that $sT=0$ for some $s\in S$. The notion of $u$-$S$-exact sequences is also introduced from the viewpoint of uniformity.
