Compactly Generated Domain Theory
... In order to address these weaknesses, it seems necessary to leave the familiar dcpobased world of traditional domain theory. One possible alternative is to identify subcategories of domain-like structures within suitable “realizability” categories, see e.g. (Phoa 1990; Longley and Simpson 1997; Reus ...
