摘要
设S是幺半群,在S-系范畴中引入了C(E′)系。通过对S-系中C(E′)性质的讨论,研究了S-系的同调分类问题,主要刻画了P(E′)幺半群的结构特征。
Let S be a monoid. C(E′) right S-acts in the category of S-acts are introduced. By C(E′) property of S-acts, homological classification problem of S-acts are investigated, and some important monoids, such as P(E′) monoids are characterized.
