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.
