Hani A. Khashan, Ece Yetkin Celikel

摘要:

设$R$是有单位元的交换环.本文引入拟$J$ -理想的概念,它是$J$ -理想的推广. $R$的真理想称为拟$J$ -理想,如果它的根是$J$ -理想.得到了某些特殊环中拟$J$ -理想的许多刻画。刻画了每个真理想都是拟$J$ -理想的环.进一步,作为可预可预环的推广,我们定义了拟可预环的概念。我们称一个环$R$为拟可予环,如果只要$a,b\in R$和$a=ab$,则要么$a$是幂零的,要么$b$是单位元.证明了包含在Jacobson根中的真理想$I$是拟$J$ -理想(分别为). $J$ -理想)当且仅当$R/I$是拟可预测的(分别为可预测的)环。

英文摘要:

Let $R$ be a commutative ring with identity. In this paper, we introduce the concept of quasi $J$-ideal which is a generalization of $J$-ideal. A proper ideal of $R$ is called a quasi $J$-ideal if its radical is a $J$-ideal. Many characterizations of quasi $J$-ideals in some special rings are obtained. We characterize rings in which every proper ideal is quasi $J$-ideal. Further, as a generalization of presimplifiable rings, we define the notion of quasi presimplifiable rings. We call a ring $R$ a quasi presimplifiable ring if whenever $a,b\in R$ and $a=ab$, then either $a$ is a nilpotent or $b$ is a unit. It is shown that a proper ideal $I$ that is contained in the Jacobson radical is a quasi $J$-ideal (resp. $J$-ideal) if and only if $R/I$ is a quasi presimplifiable (resp. presimplifiable) ring.
