Following a classical line, we define diagrammatic specifications as a kind of generalised sketch. In addition, the specifications themselves are defined as the realisations of projective sketches. This meta level provides adjunction properties: this is due to a well-known result of Ehresmann. Moreover, we prove in this paper that this meta level also provides an efficient definition of deduction. This work results from a collaboration with Christian Lair.<\/jats:p>","DOI":"10.1017\/s0960129503003979","type":"journal-article","created":{"date-parts":[[2003,12,23]],"date-time":"2003-12-23T12:11:39Z","timestamp":1072181499000},"page":"857-890","source":"Crossref","is-referenced-by-count":4,"title":["Diagrammatic specifications"],"prefix":"10.1017","volume":"13","author":[{"given":"DOMINIQUE","family":"DUVAL","sequence":"first","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2003,12,23]]},"container-title":["Mathematical Structures in Computer Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0960129503003979","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T22:02:37Z","timestamp":1557180157000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0960129503003979\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,12]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2003,12]]}},"alternative-id":["S0960129503003979"],"URL":"https:\/\/doi.org\/10.1017\/s0960129503003979","relation":{},"ISSN":["0960-1295","1469-8072"],"issn-type":[{"value":"0960-1295","type":"print"},{"value":"1469-8072","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,12]]}}}
