Intellectual

A Timed Specification Language for Concurrent Reactive Systems,PL. which contains timing operators and concurrency with synchronous communication. This happens . or transformation as originally advocated by Dijkstra and Wirth. We shall give the example of two rules for correct transformations. They will be applied to the example of a railway crossing.

The Static Part of the Design Language COLD-K,ains definitions of syntax and semantics, together with a presentation of the notions used in the definition of the semantics, such as MPL. (many-sorted partial infinitary logic), inductive definitions, the algebra of theories (with the operations renaming, import and export) and the type structure

Generation of Proof Obligations for Type Consistency (Extended Abstract),ype errors such as taking the head or tail of an empty list..The system has been proved sound and complete with respect to a denotational semantics of the language. In this semantics, the head of an empty list is the special element ., denoting type error, and not ⊥ which is used only for modelling

Towards Proof Rules for Looseness in Explicit Definitions from VDM-SL,but now a standard for the language has been prepared, including a dynamic semantics defined from a model-theoretic point of view. Thus, it is not at all clear that the defined semantics is appropriate for deriving proof rules which reflect the semantics. This paper focus on the possible ways of def
