Abstract. We present a new combination CSP-OZ-DC of three well researched formal techniques for the specification of processes, data and time: CSP [17], Object-Z [36], and Duration...
The tautology problem is the problem to prove the validity of statements. In this paper, we present a calculus for this undecidable problem on graphical conditions, prove its sound...
We introduce a notion of Kripke model for classical logic for which we constructively prove soundness and cut-free completeness. We discuss the meaning of the new notion and its a...
Building on previous work by Coquand and Spiwack [8] we construct a strict domaintheoretic model for the untyped -calculus with pattern matching and term rewriting which has the p...
We construct a language extension for process calculi for modelling the exchange of cryptographically composed data. More specifically, we devise a succinct syntax for terms and ...
