Domain Theory and the Logic of Observable Samson Abramsky

Summary: Domain Theory and the Logic of Observable

The mathematical framework of Stone duality is used to synthesize a number
of hitherto separate developments in Theoretical Computer Science:
Domain Theory, the mathematical theory of computation introduced
by Scott as a foundation for denotational semantics.
The theory of concurrency and systems behaviour developed by Milner,
Hennessy et al. based on operational semantics.
Logics of programs.
Stone duality provides a junction between semantics (spaces of points =
denotations of computational processes) and logics (lattices of properties of
processes). Moreover, the underlying logic is geometric, which can be com-
putationally interpreted as the logic of observable properties--i.e. properties
which can be determined to hold of a process on the basis of a finite amount
