First, we consider topological models, and then extend our discussion to a more expressive model, namely, subset space models. Furthermore, we prove the completeness of public announcement logic in those frameworks. After that, we apply our results to different issues: announcement stabilization, backward induction and persistence.<\/jats:p>","DOI":"10.3233\/fi-2012-710","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T00:08:51Z","timestamp":1575331731000},"page":"207-223","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Public Announcement Logic in Geometric Frameworks"],"prefix":"10.1177","volume":"118","author":[{"given":"Can","family":"Ba\u015fkent","sequence":"first","affiliation":[{"name":"Department of Computer Science, The Graduate Center, The City University of New York, 365 Fifth Avenue, New York, NY 10016, USA, cbaskent@gc.cuny.edu www.canbaskent.net"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,1,1]]},"container-title":["Fundamenta Informaticae"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2012-710","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2012-710","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T06:30:05Z","timestamp":1777444205000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/FI-2012-710"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,1,1]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2012,9]]}},"alternative-id":["10.3233\/FI-2012-710"],"URL":"https:\/\/doi.org\/10.3233\/fi-2012-710","relation":{"is-cited-by":[{"id-type":"doi","id":"10.4204\/EPTCS.251.7","asserted-by":"object"},{"id-type":"doi","id":"10.4204\/EPTCS.215.20","asserted-by":"object"}]},"ISSN":["0169-2968","1875-8681"],"issn-type":[{"value":"0169-2968","type":"print"},{"value":"1875-8681","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,1,1]]}}}
