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 ...

𝐾₁ of a commutative von Neumann regular ring

, 1972
Let A be a commutative regular ring (in the sense of von Neumann), and let q be an ideal in A. Then K 1 ( A , q ) = U ( A , q

Classification of Boolean algebras through von Neumann regular $\mathcal{C}^{\infty}-$rings [PDF]

In this paper, we introduce the concept of a ``von Neumann regular $\mathcal{C}^{\infty}$-ring", which is a model for a specific equational theory.

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 ...

On rational extensions of a ring [PDF]

, 1971
The purpose of this paper is to examine the rational extensions of a ring and to prove that under certain conditions the injective hull of a ring is a right self-injective, von Neumann ring.
