Konstruksi Ring Bersih dari Sebarang Ring

open access: yesJurnal Matematika, 2015
The aims of this research was to construct a clean ring from any ring.  The base on the fact  that the endomorphism ring of every pure-injective module is clean, it was constructed a clean ring from any ring. So, the result of this research was it always

Modules in which every surjective endomorphism has an e-small kernel

open access: yesJournal of Kufa for Mathematics and Computer, 2023
In this paper we introduce the notion of e-gH modules which is a proper generalization of Hopfian modules and defined as, a module  is called e-gH if, any surjective -endomorphism  of  has an e-small kernel, a ring  is called e-gH if,  is e-gH. We

Nilpotent graphs of skew polynomial rings over non-commutative rings [PDF]

open access: yesTransactions on Combinatorics, 2020
Let $R$ be a ring and $\alpha$ be a ring endomorphism of $R$‎. ‎The undirected nilpotent graph of $R$‎, ‎denoted by $\Gamma_N(R)$‎, ‎is a graph with vertex set $Z_N(R)^*$‎, ‎and two distinct vertices $x$ and $y$ are connected by an edge if and only if ...

Pairing-based algorithms for jacobians of genus 2 curves with maximal endomorphism ring [PDF]

open access: yes, 2012
Using Galois cohomology, Schmoyer characterizes cryptographic non-trivial self-pairings of the $\ell$-Tate pairing in terms of the action of the Frobenius on the $\ell$-torsion of the Jacobian of a genus 2 curve.

Universal deformation rings and tame blocks [PDF]

open access: yes, 2013
Let k be an algebraically closed field of positive characteristic, and let W be the ring of infinite Witt vectors over k. Suppose G is a finite group and B is a block of kG of infinite tame representation type. We find all finitely generated kG-modules V

Explicit CM-theory for level 2-structures on abelian surfaces [PDF]

open access: yes, 2011
For a complex abelian variety $A$ with endomorphism ring isomorphic to the maximal order in a quartic CM-field $K$, the Igusa invariants $j_1(A), j_2(A),j_3(A)$ generate an abelian extension of the reflex field of $K$.

On the trace of permuting tri-derivations on rings

open access: yesМатематичні Студії, 2022
In the paper we examined the some effects of derivation, trace of permuting tri-derivation and endomorphism on each other in prime and semiprime ring. Let $R$ be a $2,3$-torsion free prime ring and $F:R\times R\times R\rightarrow R$ be a permuting tri ...

Fredholm modules over categories, Connes periodicity and classes in cyclic cohomology

open access: yesComptes Rendus. Mathématique, 2023
We replace a ring with a small $\mathbb{C}$-linear category $\mathcal{C}$, seen as a ring with several objects in the sense of Mitchell. We introduce Fredholm modules over this category and construct a Chern character taking values in the cyclic ...

Some Notes on Semiabelian Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
It is proved that if a ring R is semiabelian, then so is the skew polynomial ring R[x;σ], where σ is an endomorphism of R satisfying σ(e)=e for all e∈E(R). Some characterizations and properties of semiabelian rings are studied.
