A Denotational Semantics for First-Order Logic

In Apt and Bezem [AB99) we provided a computational interpretation of first-order formulas over arbitrary interpretations. Here we complement this work by introducing a denotational semantics for first-order logic. Additionally, by allowing an assignment of a non-ground term to a variable we introduce in this framework logical variables. The semantics combines a number of well-known ideas from ...

Denotational Semantics of Evaluation Order in Expressions with Side Effects

The presence of side effects in even a very simple language of expressions gives rise to a number of semantic questions. The issue of evaluation order becomes a crucial one and, unless a strict order is enforced, the language becomes non-deterministic. In this paper we study the semantics of such a language under a variety of possible evaluation strategies, from simpler to more complex, conclud...

A fully abstract denotational semantics for the calculus of higher-order communicating systems

In this paper we study the Calculus of Higher Order Communicating Systems (CHOCS) (Thomsen, Proc. of POPL’89, ACM, 1989, pp. 143–154; Inform. Comput. 116(1) (1995) 38–57) in a denotational setting. We present a construction of a denotational semantics for CHOCS which resides in a domain constructed using the standard constructions of separated sum, Cartesian product, the Plotkin power domain co...

A Modular Theory of Object Orientation in Higher-Order UTP

Hoare and He’s Unifying Theories of Programming (UTP) is a framework that facilitates the integration of relational theories. None of the UTP theories of object orientation, however, supports recursion, dynamic binding, and compositional method definitions all at the same time. In addition, most of them are defined for a fixed language and do not lend themselves easily for integration with othe...
