Abstract

An observational notion of implementation for algebraic specifications is presented which formalizes the intuitive idea that an implementation is correct if it produces correct observable output. Based on a theory of observational specifications proof theoretic criteria for implementation relations are provided and a proof technique (called "context induction") for the verification of observational implementation relations is presented. As an example an abstract specification of (the algebraic semantics of) a small imperative programming language is implemented by a state oriented specification of the language.
