交完备与序Domain代数
Meet-completions and ordered domain algebras
摘要:
利用偏序集的交完备化与标准闭包算子之间的等价性,给出了构造保序偏序集展开的交完备化的一般方法。利用这种方法,我们找到了序Domain代数的交完备化,它同时也是这类代数的表示的基,从而证明了序Domain代数具有有限表示性质.我们证明了许多定义有序域代数的方程在这个完备化中被保留,但结合性(D2)和(D6)可能失败。
英文摘要:
Using the well-known equivalence between meet-completions of posets and standard closure operators we show a general method for constructing meet-completions for isotone poset expansions. With this method we find a meet-completion for ordered domain algebras which simultaneously serves as the base of a representation for such algebras, thereby proving that ordered domain algebras have the finite representation property. We show that many of the equations defining ordered domain algebras are preserved in this completion but associativity, (D2) and (D6) can fail.
