We present a semantics for fault tree analysis, a technique used for the analysis of safety critical systems, in the real-time interval logic Duration Calculus with Liveness and sh...
Abstract. The Spectrum project concentrates on the process of developing well-structured, precise system speci cations. Spectrum is a speci cation language, with a deduction calcul...
In this paper we introduce a logic for parametric polymorphism. Just as LCF is a logic for the simply-typed λ-calculus with recursion and arithmetic, our logic is a logic for Sys...
The Edinburgh Logical Framework (LF) provides a means to define (or present) logics. It is based on a general treatment of syntax, rules, and proofs by means of a typed -calculus ...
Subtyping in first order object calculi is studied with respect to the logical semantics obtained by identifying terms that satisfy the same set of predicates, as formalised throu...
