ON NIL-SYMMETRIC RINGS AND MODULES SKEWED BY RING ENDOMORPHISM

Science Journal of University of Zakho
The symmetric property plays an important role in non-commutative ring theory and module theory.  In this paper, we study the symmetric property with one element of the ring  and two nilpotent elements of  skewed by ring endomorphism  on rings ...

Additive maps preserving determinant on module of symmetric matrices over Zm

Journal of Hebei University of Science and Technology, 2018
In order to characterize the additive maps preserving of modulus of symmetric matrices over residue class rings, these maps are firstly proved to be linear in fact, then they are classified and discussed by means of contract transformation, number theory

Reversible and symmetric rings

Journal of Pure and Applied Algebra, 2002
A ring is called right (resp. left) duo if every right (resp. left) ideal is two-sided. A ring \(R\) is said to be reversible if \(ab=0\) is equivalent to \(ba=0\) for all \(a,b\in R\). A stronger condition than reversible is symmetric. A ring \(R\) is called symmetric if \(abc=0\) if and only if \(acb=0\) for all \(a,b,c\in R\). In this paper, precise

Notes on Semiprime Ideals with Symmetric Bi-Derivation

Axioms
In this paper, we prove many algebraic identities that include symmetric bi-derivation in rings which contain a semiprime ideal. We intend to generalize previous results obtained for semiprime rings with symmetric derivation using semiprime ideals in ...

A STUDY ON TRI REVERSIBLE RINGS [PDF]

Journal of Algebraic Systems
This article embodies a ring theoretic property which, preserves the reversibility of elements at non-zero tripotents. A ring R is defined as quasi tri reversible if any non-zero tripotent element ab of R implies ba is also a tripotent element in R for a,

Reversible Rings with Involutions and Some Minimalities

The Scientific World Journal, 2013
In continuation of the recent developments on extended reversibilities on rings, we initiate here a study on reversible rings with involutions, or, in short, *-reversible rings. These rings are symmetric, reversible, reflexive, and semicommutative.

Crossing-symmetric rings, ladders, and exchanges [PDF]

Physics Letters B, 1983
A new approach is used in the description of fermion and boson systems at zero or finite temperature. We generalize the familiar ladder and chaining operations to construct a crossing-symmetric approximation to the two-particle vertex from the bare interaction. The explicit rules for this construction are given in terms of Feynman propagators. The high

On group rings and some of their applications to combinatorics and symmetric cryptography [PDF]

International Journal of Group Theory, 2015
We give a survey of recent applications of group rings to combinatorics and to cryptography, including their use in the di erential cryptanalysis of block ciphers.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Witt rings of quadratically presentable fields [PDF]

Categories and General Algebraic Structures with Applications, 2020
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability.
