On von Neumann Regularity of Commutators
NK Kim, TK Kwak, Y Lee, SJ Ryu - Algebra Colloquium, 2024 - World Scientific
We study the structure of rings which satisfy the von Neumann regularity of commutators,
and call a ring R C-regular if ab− ba∈(ab− ba) R (ab− ba) for all a, b in R. For a C-regular …

On quasi-injectivity and von Neumann regularity
RY Chi Ming - Monatshefte für Mathematik, 1983 - Springer
The purpose of this note is to consider certain connections between injectivity, p-injectivity
and a generalisation of quasi-injectivity noted GQ-injectivity (cf. definition below). It is proved …

[PDF][PDF] Regularities of rings
C Roos - 1975 - Citeseer
The purpose of this thesis is to develop a general theory of regularities for rings. In ring
theory many so-called regularities appear. The oldest one seems to be the von Neumann …

Annihilation of ideals in commutative rings.
JA Huckaba, JM Keller - 1979 - msp.org
1* Introduction* An important theorem in commutative ring theory is that if/is an ideal in a

On semicommutative II-regular rings
A Badawi - Communications in algebra, 1994 - Taylor & Francis
Introduction. Let K be a ring with 1 and acK. If for every bcK there exist r, hcK such that ab=
ra and ba= ah, then a is called semicommutative. If every element of K is semicommutative …
