K1 of noncommutative von Neumann regular rings [PDF]

, 1976
If R is any (noncommutative, von Neumann) regular ring with 2 invertible, then K1 of the free (noncommuting) R-algebra on a set X is canonically isomorphic to K1(R).

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

Kochen-Specker theorem for von Neumann algebras [PDF]

, 2005
The Kochen-Specker theorem has been discussed intensely ever since its original proof in 1967. It is one of the central no-go theorems of quantum theory, showing the non-existence of a certain kind of hidden states models. In this paper, we first offer a

A characterization of graded von Neumann regular rings with applications to Leavitt path algebras

, 2021
We prove a new characterization of graded von Neumann regular rings involving the recently introduced class of nearly epsilon-strongly graded rings. As our main application, we generalize Hazrat's result that Leavitt path algebras over fields are graded ...

K-Theoretically Simple Von Neumann Regular Rings [PDF]

, 1995
The differences between simplicity of a von Neumann regular ring and simplicity of its ordered Grothendieck group K0 are investigated. In particular, we construct examples of stably finite regular rings which are not simple but have simple K0.

ON VON NEUMANN REGULARITY, INJECTIVITY AND FLATNESS [PDF]

application/pdfIt is still unknown whether a SF-ring A (every simple left or right A-module is flat) is von Neumann regular. The following non-trivial generalization of regular rings is considered: write "￥A satisfies(*)" if, for any maximal right ideal ＄

Square-difference factor absorbing submodules of modules over commutative rings

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let R be a commutative ring with identity and M an unitary R-module. Recently, in [5], Anderson, Badawi and Coykendalla defined a proper ideal I of R to be a square-difference factor absorbing ideal (sdf-absorbing ideal) of R if whenever a2 − b2 ∈ I for ...

Equilibrio competitivo y soportes del crecimiento en el modelo de Von Neumann [PDF]

This paper shows the existence of a reproducible competitive equilibrium in the general Von Neumann growth model, extending in this way a result due to Roemer.

Leavitt path algebras are graded von Neumann regular rings

, 2014
In sharp contrast to the Abrams–Rangaswamy theorem that the only von Neumann regular Leavitt path algebras are exactly those associated to acyclic graphs, here we prove that the Leavitt path algebra of any arbitrary graph is a graded von Neumann regular ...
