Metasoft primer: Towards a metalanguage for applied denotational semantics

Towards a denotational semantics for ET-LOTOS

The formal speciication language LOTOS is an international standard for use in Open Systems Interconnection. A timed extension called ET-LOTOS has been proposed. This paper presents a fully-abstract denotational semantics for the process algebraic component of this extension. The beneets of a denotational semantics are discussed, as are the applications.

Towards a Denotational Semantics for Discrete-Event Systems

This work focuses on establishing a semantic interpretation for discrete-event systems. In this paper we describe some of the basic mathematical structures, building on the tagged-signal model of [4, 3], and the term-based formalism of [5].

Towards a Denotational Semantics for Concurrent State Transformers

Concurrent state transformers are an extension of state transformers investigated by Launchbury, Peyton Jones, Wadler, and others by concurrency primitives. A denotational semantics for state transformers executing in parallel is deened using standard domain theoretic techniques. Using the semantics it is proved that concurrent state transformers still form a monad and that the concurrent seman...

A Denotational Semantics for Circus

Circus specifications define both data and behavioural aspects of systems using a combination of Z and CSP. Previously, a denotational semantics has been given to Circus; however, as a shallow embedding of Circus in Z, it was not possible to use it to prove properties like the refinement laws that justify the distinguishing development technique associated with Circus. This work presents a fina...
