摘要
本文研究了Abelπ-正则环的扩张.利用环的结构理论,证明了一个Abel环R(不必有1)是π-正则的当且仅当有理想I使得I和R/I都是π-正则的.推广了一些文献的结论.
In this paper we study extensions of Abelian π-regular rings. Using theory of ring structure, we prove that an Abelian ring R (not necessarily with 1) is π-regular if and only if both I and R/I are π- regular for an ideal I of R. Results in this paper generalize some results in the literature.
