研究了环的S -弱正则性,得到S -弱正则性刻画的一个充分必要条件,即设R是环,J是R的任何理想,则R是S -弱正则环〈=〉R/J和J都是S -弱正则环.另一部分讨论了半群环和收缩半群环的S -弱正则性,得到一些重要性质.
In this paper, we study the s-weakly regularity of rings. On this basis, we show that :if R is a ring, J is an ideal of R,then R is an S -weakly regular ring if R/J and J only if and are s-weakly regular rings. Next, we give some characterizations of s-weakly regularity of semigroup rings and constracted semigroup ring.
