\({\mathcal Z}\)-continuous posets and their topological manifestation. (English) Zbl 0939.06005

A subset collection \({\mathcal Z}\) assigns to each poset \(P\) a certain collection \({\mathcal Z}P\) of subsets. The theory of topological or algebraic closure spaces extends to the general \({\mathcal Z}\)-level, by replacing directed or finite sets with arbitrary \({\mathcal Z}\)-sets and leads to a theory of \({\mathcal Z}\)-union completeness, \({\mathcal Z}\)-arity, \({\mathcal Z}\)-soberness etc.
The author shows that the category of strongly \({\mathcal Z}\)-continuous posets (with interpolation) is concretely isomorphic to the category of \({\mathcal Z}\)-ary \({\mathcal Z}\)-complete core spaces. His paper contains the theory of \({\mathcal Z}\)-continuous posets, the fundamental setting of subset selections, various connections between union completeness, \({\mathcal Z}\)-arity and generalized soberness, the algebraic theory of \({\mathcal Z}\)-distributivity and \({\mathcal Z}\)-continuous posets and some topological aspects.
