Roughly speaking, an explicit Henkin sentence not only asserts its own provability, as ordinary Henkin sentences do, but explicitly provides a detailed description of a proof. We provide, in this paper, a precise formalization of Hofstadter's notion and then show that true explicit Henkin sentences exist.<\/jats:p>","DOI":"10.2307\/2273791","type":"journal-article","created":{"date-parts":[[2006,5,6]],"date-time":"2006-05-06T22:12:14Z","timestamp":1146953534000},"page":"91-93","source":"Crossref","is-referenced-by-count":4,"title":["Explicit Henkin sentences"],"prefix":"10.1017","volume":"50","author":[{"given":"Robert M.","family":"Solovay","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,3,12]]},"reference":[{"key":"S0022481200033090_ref002","first-page":"115","volume":"20","author":"L\u00f6b","year":"1955","journal-title":"Solution of a problem of Leon Henkin"},{"key":"S0022481200033090_ref001","volume-title":"G\u00f6del, Escher, Bach: an eternal golden braid","author":"Hofstadter","year":"1979"}],"container-title":["Journal of Symbolic Logic"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022481200033090","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,22]],"date-time":"2019-05-22T23:22:35Z","timestamp":1558567355000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022481200033090\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1985,3]]},"references-count":2,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1985,3]]}},"alternative-id":["S0022481200033090"],"URL":"https:\/\/doi.org\/10.2307\/2273791","relation":{},"ISSN":["0022-4812","1943-5886"],"issn-type":[{"value":"0022-4812","type":"print"},{"value":"1943-5886","type":"electronic"}],"subject":[],"published":{"date-parts":[[1985,3]]}}}
