摘要: 首先, 证明含单位元的结合环R是左广义弱零插入(GWZI)环当且仅当对任意的a,b∈R, ab=0蕴含存在正整数n, 使得anRb=0; 其次, 利用矩阵分块方法证明环R是左GWZI环当且仅当对任意的整数n≥2, Sn(R)是左GWZI环.

关键词: 半交换环, 广义弱(GW)-理想, 左GWZI环

Abstract: Firstly, we prove that a unital associative ring R is a left generalized weak zero insertive (GWZI) ring if and only if ab=0 implies anRb=0 for some positive integer n. Secondly, we prove that a ring R is a left GWZI ring if and only if so is Sn(R) for any integer n≥2 by using the method of matrix partition.

Key words: semicommutative ring, generalized weak (GW)-ideal, left GWZI ring
