Generalized derivations with power values on rings and Banach algebras [PDF]

Mathematica Bohemica
Let $R$ be a prime ring and $I$ a nonzero ideal of $R.$ The purpose of this paper is to classify generalized derivations of $R$ satisfying some algebraic identities with power values on $I.$ More precisely, we consider two generalized derivations $F$ and

Strongly Invo. T- Clean Rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics
In this paper, we present the idea of a strongly invo. T-clean rings, which we define as rings with every a in R having the formula a = t + v, where t is a tripotent and v is an order two unit that commute.

On Semiabelian π-Regular Rings

International Journal of Mathematics and Mathematical Sciences, 2007
A ring R is defined to be semiabelian if every idempotent of R is either right semicentral or left semicentral. It is proved that the set N(R) of nilpotent elements in a π-regular ring R is an ideal of R if and only if R/J(R) is abelian, where J(R) is ...

HOMOGENEOUS IDEALS AND JACOBSON RADICAL

Proceedings of the YSU A: Physical and Mathematical Sciences, 2017
In this paper the Jacobson radical of an algebra$F\langle X\rangle / H$ is studied, where FhXi is a free associative algebra of countable rank over infinite field $F$ and $H$ is a homogeneous ideal of the algebr$F\langle X\rangle$. The following theorem is proved: the Jacobson radical of an algebra $F\langle X\rangle / H$ is a nil ideal.

Rad-⊕-Supplemented Modules

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this paper we provide various properties of Rad-⊕-supplemented modules. In particular, we prove that a projective module M is Rad- ⊕-supplemented if and only if M is ⊕-supplemented, and then we show that a commutative ring R is an artinian serial ring

The Arens-Calderon theorem for commutative topological algebras

Extracta Mathematicae
A theorem of Arens and Calderon states that if A is a commutative Banach algebra with Jacobson radical Rad(A), and if a0 , . . . , an∈ A with a0 ∈ Rad(A) and a1 an invertible element of k A, then there exists y ∈ Rad(A) such that Σ ak yk = 0.

基本弱Hopf代数和弱覆盖箭图(Basic weak Hopf algebra and weak covering quiver)

Zhejiang Daxue xuebao. Lixue ban, 2016
We introduce a finite-dimensional basic and split weak Hopf algebra H over an algebraically closed field k with strongly graded Jacobson radical r. We obtain some structures of a finite-dimensional basic and split semilattice graded weak Hopf algebra,and

El radical de Jacobson

, 1986
El objetivo principal de esta monografía ha sido el de reunir en un solo texto algunas de las definiciones de radical, e ir mostrando a lo largo de esta, como cada nueva definición contiene a la anterior como caso particular. En el primer capítulo estudiaremos sucesivamente el radical de un anillo conmutativo con unidad, de un anillo con unidad y de ...
