An Axiomatic Value Model for Isabelle/UTP
[chapter]
2017
Lecture Notes in Computer Science
Preserved Fulltext
Several mechanisations of the UTP in HOL theorem provers have been developed. All of them, however, succumb to a trade off in how they encode the value model of UTP theories. ...
The Unifying Theories of Programming (UTP) is a mathematical framework to define, examine and link program semantics for a large variety of computational paradigms. ...
Acknowledgement We would like to thank the anonymous reviewers for their helpful suggestions and conscientious reading of the paper. ...

In this paper, we contribute a formal machine-checked interactive language for the computer-assisted construction of ACs called Isabelle/SACM. ...
However, ACs can rarely be fully formalised, as the use of FMs is contingent on models that are validated by informal processes. ...
Normally, claims are in natural languages, but in SACM they can also contain structured expressions, which allows integration of formal languages. The argumentation meta-model is shown in Figure 3 . ...

Its primary design goal was to support the higher-order logic, alphabets, equational reasoning and "programs as predicates" style that is prevalent in much of the UTP literature, from the seminal work ...
These key features include: a formalisation of a UTP Theory; support for common proof strategies; sophisticated goal/law matching ; and user-defined language constructs. ...
Within the UTP community, there has been considerable work using Proof-Power-Z to build models of UTP theories in Z in order to mechanise proofs. ...
