A Development Calculus for Specifications [article]

Wei Li
2003 arXiv   pre-print
A first order inference system, called R-calculus, is defined to develop the specifications. It is used to eliminate the laws which is not consistent with the user's requirements.  ...  The R-calculus consists of the structural rules, an axiom, a cut rule, and the rules for logical connectives. Some examples are given to demonstrate the usage of the R-calculus.  ...  For a given Γ ⊢ A, the R-calculus is used to derive all maximal contractions of Γ by ¬A.  ...

Formal Specification and Verification of Complex Systems1 1Work partially founded by Miur projectSP4

S. Gnesi
2003 Electronical Notes in Theoretical Computer Science  
Recently a verification environment, HAL [7] , for the π-calculus has been developed The construction of the verification environment takes a direct advantage of the finite representation of π-calculus  ...  Hence, even though the π-calculus generalizes CCS [16] , the semantic-based verification tools developed for CCS cannot be directly reused for the π-calculus.  ...

A practical approach to software engineering using Z and the refinement calculus

Kenneth R. Wood
1993 Software engineering notes  
We present a methodology for the formal spectficataon and development of software systems ustng Z and the  ...  For example, King [9] gives rules for translating Z specifications into Morgan's refinement calculus [12], after which the laws of the calculus can be used to develop the specification  ...  In particular, Morgan's calculus is highly developed and its laws have been codified and collected in such a way that it can be used to develop real programs from abstract specifications  ...

Performance Certification of Software Components

Erik Burger, Ralf Reussner
2011 Electronical Notes in Theoretical Computer Science  
In a distributed process of software development, this means that quality requirements must be made explicit in the specification, and the developing party of a commissioned component needs to deliver  ...  We extend the notion of model refinement to non-functional properties of software and propose a refinement calculus for conformance checking between abstract performance descriptions of components.  ...  The contribution of this paper is firstly a model for parameterised component performance specifications and secondly a calculus of refinement.  ...

A Theory Independent Curry-De Bruijn-Howard Correspondence [chapter]

Gilles Dowek
2012 Lecture Notes in Computer Science  
Instead of developing a customized typed lambda-calculus for each specific theory, we may attempt to design a general parametric calculus that permits to express the proofs of any theory.  ...  First, they have proposed to express these algorithms in the lambda-calculus, writing for instance λf AA⇒B λx A (f x x) for the proof of the proposition (AA ⇒ B) ⇒ A ⇒ B taking a proof f of AA ⇒  ...
