诣零可逆环

Nil-reversible rings

Sanjiv Subba, Tikaram Subedi

摘要:

本文引入并研究了零可逆环,如果环R的每个幂零元的左零化子和右零化子相等,则称环R为零可逆环。可逆环(从而也是约化环)是诣零可逆环的一个真子类,因此我们给出了诣零可逆环约化的一些条件。证明了诣零可逆环是交换的、2-原始的、弱半交换的和诣零Armendariz的。进一步,我们观察到,一般情况下,诣零可逆环R上的多项式环不一定是诣零可逆的,但如果R是附加Armendariz环,则它是诣零可逆的.

英文摘要:

This paper introduces and studies nil-reversible rings wherein we call a ring R nil-reversible if the left and right annihilators of every nilpotent element of R are equal. Reversible rings (and hence reduced rings) form a proper subclass of nil-reversible rings and hence we provide some conditions for a nil-reversible ring to be reduced. It turns out that nil-reversible rings are abelian, 2-primal, weakly semicommutative and nil-Armendariz. Further, we observe that the polynomial ring over a nil-reversible ring R is not necessarily nil-reversible in general, but it is nil-reversible if R is Armendariz additionally.
