Topological representations for frame-valued domains via $L$-sobriety

Abstract

With a frame LL as the truth value table, we study the topological representations for frame-valued domains. We introduce the notions of locally super-compact LL-topological space and strong locally super-compact LL-topological space. Using these concepts, continuous LL-dcpos and algebraic LL-dcpos are successfully represented via LL-sobriety. By means of Scott LL-topology and specialization LL-order, we establish a categorical isomorphism between the category of the continuous (resp., algebraic) LL-dcpos with Scott continuous maps and that of the locally super-compact (resp., strong locally super-compact) LL-sober spaces with continuous maps. As an application, for a continuous LL-poset PP, we obtain a categorical isomorphism between the category of directed completions of PP with Scott continuous maps and that of the LL-sobrifications of (P,σL(P))(P, \sigma_{L}(P)) with continuous maps.
