Abstract

It is possible to divide the syntax-directed approaches to programming language semantics into two classes, “denotational”, and “proof-theoretic”. This paper argues for a different approach which also has the effect of linking the two methods. Drawing on recent work on locales as formal spaces we show that this provides a way in which we can hope to use a proof-theoretical semantics to give us a denotational one. This paper reviews aspects of the general theory, before developing a modal construction on locales and discussing the view of power-domains as free non-deterministic algebras. Finally, the relationship between the present work and that of Winskel is examined.
