利用各种类型的理想刻划了π-正则半环、完全π-正则半环和拟完全π-正则半环,所得结果推广和扩充了相关文献中关于正则半环的一些结果.
Characterizations of π-regular, completelyπ-regular and quasi-completely π-regular semirings are given in terms of various types of ideals of semirings. The results of this paper generalize and expand the corresponding resules of regular semirings.
