Order isomorphisms relating Scott’s three presentations of domains — continuous lattices (1972), neighbourhood systems (PRG-19), and information systems (1982) — including the round identification D ≃o RoundFilter ≃o RoundInfoSysElement and the S-expression equation T ≅ A + (T × T) as |T| ≃o |A + (T × T)| (SexSys.Element ≃o SexRhs.Element). Not a formalization of the three papers. Account: view.pdf.
