对于偏序集P,设σ(P)和Γ(P)分别表示其Scott开子集和Scott闭子集按包含序所构成的格,并设P=(P,σ(P)).本文讨论了Γ(P)上的下Vietoris拓扑和Scott拓扑,给出了使这两个拓扑相等的充分条件.在σ(P)和σ(Γ(P))之间建立一个连接,证明了ΣP是核紧的当且仅当σ(Γ(P))是核紧的当且仅当σ(Γ(P))是sober的局部紧的且σ(Γ(P))= σ(Γ(P))(下Vietoris拓扑).这回答了[17]中的一个问题。布雷希特和Kawai [2]提出了拓扑空间X的调和是否蕴涵其下幂空间的调和的问题,本文最后给出了这个问题的部分答案。
For a poset P, let σ (P) and Γ (P) respectively denote the lattice of its Scott open subsets and Scott closed subsets ordered by inclusion, and set Σ P=(P, σ (P)). In this paper, we discuss the lower Vietoris topology and the Scott topology on Γ (P) and give some sufficient conditions to make the two topologies equal. We build an adjunction between σ (P) and σ (Γ (P)) and prove that ΣP is core-compact iff Σ Γ (P) is core-compact iff Σ Γ (P) is sober, locally compact and σ (Γ (P))= υ (Γ (P))(the lower Vietoris topology). This answers a question in [17]. Brecht and Kawai [2] asked whether the consonance of a topological space X implies the consonance of its lower powerspace, we give a partial answer to this question in the last part of this paper.
