文摘We introduce, in this paper, the right weakly p.p. rings as the generaliza- tion of right p.p. rings. It is shown that many properties of the right p.p. rings can be extended onto the right weakly p.p. rings. Relative examples are constructed. As applications, we also characterize the regular rings and the semisimple rings in terms of the right weakly p.p. rings.
文摘研究环的Ore扩张的幂零p.p.性,幂零Baer性和弱Mc Coy性,主要证明了:设R是一个拟IFP和(α,δ)-condition环,则有(1)如果R是幂零p.p.-环,则R[x;α,δ]是幂零p.p.-环;(2)如果R是幂零Baer环,则R[x;α,δ]是幂零Baer环;(3)R[x;α,δ]是右弱M c Coy环。
