The Lawson Topology on Quasicontinuous Domains

Conference paper
Part of the Semantic Structures in Computation book series (SECO, volume 1)


For a directed complete poset P, let λ(P) and σ(P) be the lower topology and the Lawson topology on P respectively. We constructively prove that if P is a quasicontinuous domain and all lower closed subsets in (P, λ(P)) are closed in (P, ω(P)),then (P,λ(P)) is strictly completely regular ordered space.
