环上的强$P$-清洁性

The strong $P$-cleanness over rings

Huanyin Chen, H. Kose, Y. Kurtulmaz

摘要:

环$R$的一个元素是强$P$-clean的,只要它可以被写为一个幂等元和一个可交换的强幂零元之和。如果环$R$的每个元素都是强$P$-干净的,则环是强$P$-干净的。本文研究了环$R$是强$P$-clean的充要条件.得到了这类环的许多特征。给出了交换局部环上$2\times 2$矩阵的强$P$-清洁性的判别准则.

英文摘要:

An element of a ring $R$ is strongly $P$-clean provided that it can be written as the sum of an idempotent and a strongly nilpotent element that commute. A ring $R$ is strongly $P$-clean in case each of its elements is strongly $P$-clean. We investigate, in this article, the necessary and sufficient conditions under which a ring $R$ is strongly $P$-clean. Many characterizations of such rings are obtained. The criteria on strong $P$-cleanness of $2\times 2$ matrices over commutative local rings are also determined.
