This construction gives rise to a functor Φfrom the category of bounded distributive lattices to itself. We examine the interaction of Φwith Priestley duality and characterise those bounded distributive lattices L such that there is a bounded distributive lattice K such that Φ(K) is (isomorphic to) L.9 pagesLogic06B50; 54F05text
