摘要
在FZ-Domain中引入FZ-定向基与FZ-抽象基的概念,研究了它们的RZ-理想完备化.证明了:对一类子集系统,一个FZ-Domain的FZ-定向基的定向RZ-理想完备化同构于该FZ-Domain;偏序集P是FZ-Domain当且仅当存在一个FZ-抽象基B使得P同构于B的定向的RZ-理想完备化.
The concepts of FZ-Directed basis and FZ-abstract basis for FZ-Domains are defined.The RZ-ideal completions of them are studied.It is proved that for one class of subset systems,every FZ-Domain is isomorphic to the direct round Z-ideal completion of its FZ-directed basis;and a poset P is an FZ-Domain if and only if there exists an FZ-abstract basis B such that P is isomorphic to the direct RZ-ideal completion of B.
