摘要: 考虑WGP-内射环的极大零化子的性质, 证明了若一个左WGP-内射环R满足对任意无限个元素a1,a2,a3,…, 均有左零化子构成的升链l(a1)l(a1a2)l(a1a2a3)…是稳定的, 则: R是半准素环; R是左、 右完全环; R是左、 右Kasch环. 并给出WGP-内射环的一些充要条件.

关键词: GP-内射环, WGP-内射环, 半单环, 极小内射环

Abstract: We considered some properties of maximal annihilators of WGPinjective rings, and proved that: if a left WGPinjective ring R satisfied that the ascending chain l(a1)l(a1a2)l(a1a2a3)… consisting left annihilator were stable for arbitrary infinite element a1,a2,a3,…,  then R was a semiprimary ring; R was a left and right perfect ring; and R was a left and right Kasch ring. Some sufficient and necessary conditions of WGPinjective rings were given.

Key words: semisimple ring, mininjective ring, WGPinjective ring, GPinjective ring
