摘要
本文在偏序集上引入并考察相对定向集的概念,并证明当T定向时,偏序集上所有相对T的定向集构成一个完备格。此外,引入相对定向完备集的概念,并探讨定向完备集、一致完备集与相对定向完备集之间的关系。
In the paper,we introduce and examine the relative directed sets on posets. We obtain that the family of all directed sets reative to the directed set T on posets is a complete lattice. On the basis,we will further study the relationship between directed complete set,uniformly complete set and relative directed complete set.
