摘要
本文研究了有限链上的部分保序变换半群PO_n.通过对其幂等元的分析,获得了PO_n的极大正则子半群和极大幂等元生成子半群的结构与分类.
In this article,the semigroup PO_n,consisting of all singular partial orderpreserving transformations on a finite chain,is studied.By analyzing the idempotent elements, we completely obtain the structure and classification of the maximal regular subsemigroups,the maximal idempotent-generated subsemigroups of PO_n.
