摘要: S是幺半群,研究正则右系的一个推广,称之为主弱C(P)-系。一个右S-A 称为主弱C(P)系,如果A的所有循环子系满足条件(PWP)。通过主弱C(P)性质刻画了主弱P(P)幺半群的特征,研究了关于主弱C(P)性质的同调分类问题。

关键词: S-系, 主弱C(P)系, 主弱P(P)幺半群

Abstract: Let S be a monoid. A generalization of regular right act is studied, which is called principally weakly C(P)act. A right S-act A is called a principally weakly C(P)act if all cyclic subacts of A satisfy condition(PWP). The characterization of principally weakly P(P)monoids are mainly characterized by principally weakly C(P)properties, the homological classification problem on principally weakly C(P)acts is investigated.

Key words: S-acts, principally weakly C(P)act, principally weakly P(P)monoid
