Nevertheless, in the general case, this notion is inadequate for revision, where it is replaced by maximal consistent subsets. A natural question is whether this latter notion allows for a definition of contraction-like operators and, in case it does, what differences there exist w.r.t. standard contraction. We make some steps towards this direction for the case of graded expansions of one of the most prominent fuzzy logics, &amp;Lstrok;ukasiewicz logic. We characterize contraction operators with a fixed security-threshold &amp;epsiv;&amp;gt;0; we prove soundness of (an optimal) &amp;omega;-contraction operation, and a collapse theorem from &amp;omega;- to some &amp;epsiv;-contraction for finite theories.<\/jats:p>","DOI":"10.3233\/978-1-60750-061-2-265","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:27:24Z","timestamp":1740133644000},"source":"Crossref","is-referenced-by-count":0,"title":["Secure and Optimal Base Contraction in Graded &amp;Lstrok;ukasiewicz Logics"],"prefix":"10.3233","author":[{"family":"Pardo Pere","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Dellunde Pilar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Godo Llu&iacute;s","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Artificial Intelligence Research and Development"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:45:54Z","timestamp":1740134754000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=202&spage=265"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-061-2-265","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2009]]}}}
