|
Abstract:
摘要： 设S是序幺半群, 在S上定义了满足条件(E')的序S-系, 引入了序S-系的弱拉回平坦性, 并研究了右Rees商序S-系对于序幺半群的同调分类问题。
Abstract: LetS be a pomonoid. S-poset satisfying condition (E') is defined and weakly pullback flatness is given over pomonoid. Furthermore, the homological classifications of pomonoids by their Rees factor S-posets are investigated
