Projectivity and flatness over the endomorphism ring of a finitely generated module [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2004
Let A be a ring and Λ a finitely generated A-module. We give necessary and sufficient conditions for projectivity and flatness of a module over the endomorphism ring of Λ.

QUOTIENT SEMINEAR-RINGS OF THE ENDOMORPHISM OF SEMINEAR-RINGS

open access: yesBarekeng, 2022
A seminear-ring is a generalization of ring. In ring theory, if  is a ring with the multiplicative identity, then the endomorphism module  is isomorphic to . Let  be a seminear-ring.

On weakened $(\alpha,\delta)$-skew Armendariz rings [PDF]

open access: yesMathematica Bohemica, 2022
In this note, for a ring endomorphism $\alpha$ and an $\alpha$-derivation $\delta$ of a ring $R$, the notion of weakened $(\alpha,\delta)$-skew Armendariz rings is introduced as a generalization of $\alpha$-rigid rings and weak Armendariz rings.

On skew power series over McCoy rings [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
Let $R$ be a ring with an endomorphism $\alpha$‎. ‎A ring $R$ is a skew power series McCoy ring if whenever any non-zero power series $f(x)=\sum_{i=0}^{\infty}a_ix^i,g(x)=\sum_{j=0}^{\infty}b_jx^j\in R[[x;\alpha]]$ satisfy $f(x)g(x)=0$‎, ‎then there ...

The Baer–Kaplansky Theorem for all abelian groups and modules

open access: yesBulletin of Mathematical Sciences, 2022
It is shown that the Baer–Kaplansky Theorem can be extended to all abelian groups provided that the rings of endomorphisms of groups are replaced by trusses of endomorphisms of corresponding heaps.

Bi-clean and clean Hopf modules

open access: yesAIMS Mathematics, 2022
Let $ R $ be a commutative ring with multiplicative identity, $ C $ a coassociative and counital $ R $-coalgebra, $ B $ an $ R $-bialgebra. A clean comodule is a generalization and dualization of a clean module.

Prime ideal on the end_Z (Z^n ) Ring

open access: yesAl-Jabar, 2022
The set of all endomorphisms over -module  is a non-empty set denoted by . From  we can construct the ring of  over addition and composition function. The prime ideal is an ideal which satisfies the properties like the prime numbers.

Involution on prime rings with endomorphisms

open access: yesAIMS Mathematics, 2020
Let $\mathcal{R}$ be a prime ring with involution $'*'$ and $\psi: \mathcal{R} \rightarrow \mathcal{R}$ be an endomorphism on $\mathcal{R}$. In this article, we study the action of involution $'*',$ and the effect of endomorphism $\psi$ satisfying $[\psi(

Tilting preserves finite global dimension

open access: yesComptes Rendus. Mathématique, 2020
Given a tilting object of the derived category of an abelian category of finite global dimension, we give (under suitable finiteness conditions) a bound for the global dimension of its endomorphism ring.

A first Catalgorithm? [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2018
We propose building a new PKC in a ring structure, the classification of rings being an open problem. The difficulty of the scheme is based on retrieving the eigenvalues of endomorphism on a finite type module over a non-commutative ring. It is resistant
