On (unit-) regular morphisms
We introduce a symmetry property for unit-regular rings as follows: a∈ R is unit-regular if
and only if aR⊕(a− u) R= R (equivalently, Ra⊕ R (a− u)= R) for some unit u of R if and only …

[HTML][HTML] Morphic rings and unit regular rings
A ring R is called left morphic if R/Ra≅ l (a) for every a∈ R. A left and right morphic ring is
called a morphic ring. If Mn (R) is morphic for all n≥ 1 then R is called a strongly morphic …

A theorem on unit-regular rings
Let R be a unit-regular ring and let σ be an endomorphism of R such that σ (e)= e for all e2=
e∈ R and let n≥ 0. It is proved that every element of R [x; σ]/(xn+ 1) is equivalent to an …

Correct classes of modules
R Wisbauer - 2004 - dspace.luguniv.edu.ua
For a ring R, call a class C of R-modules (pure-) mono-correct if for any M, N∈ C the
existence of (pure) monomorphisms M→ N and N→ M implies M≃ N. Extending results and …

-regular modules
GN Sudharshana, D Sivakumar - Missouri Journal of Mathematical …, 2023 - projecteuclid.org
The notion of $ R $-regular module is introduced. We will show that if $ M $ is a torsion-free
module over a commutative ring, then $ M $ is $ R $-regular module if and only if $ M $ is a …

A study of modules over rings and their extensions
SA Al-Hashmi, SK Nauman - Ukrains' kyi Matematychnyi Zhurnal, 2018 - umj.imath.kiev.ua
We study the transfer of properties of some types of modules under identity preserving ring
homomorphisms. These studies seem to be overlooked in literature. We have picked a few …
