As a metalanguage for specifying programs and program properties we adopt constraint logic programming (CLP), and we present a set of transformation rules (including the familiar unfolding and folding rules) which preserve the semantics of CLP programs. Then, we show how program transformation strategies can be used, similarly to theorem proving tactics, for guiding the application of the transformation rules and inferring the properties to be proved. We work out three examples: (i) the proof of predicate equivalences, applied to the verification of equality between CCS processes, (ii) the proof of first order formulas via an extension of the quantifier elimination method, and (iii) the proof of temporal properties of infinite state concurrent systems, by using a transformation strategy that performs program specialization. date: 2013 date_type: completed publication: Fundamenta Informaticae volume: 127 number: 1-4 publisher: IOS Press pagerange: 115-134 id_number: 10.3233/FI-2013-899 refereed: TRUE issn: 1875-8681 official_url: http://iospress.metapress.com/content/0480055u62738804/?p=3456de1a2cbc47178e8f67e94b991d32&pi=0 citation: Fioravanti, Fabio and Pettorossi, Alberto and Proietti, Maurizio and Senni, Valerio Proving theorems by program transformation.
