We first provide a comprehensive analysis of the expressiveness of SETAFs under conflict-free, naive, stable, complete, admissible and preferred semantics. Our analysis shows that SETAFs are strictly more expressive than Dung AFs. Towards a uniform characterization of SETAFs and Dung AFs we provide general results on expressiveness which take the maximum degree of the collective attacks into account. Our results show that, for each k&amp;gt;0, SETAFs that allow for collective attacks of k+1 arguments are more expressive than SETAFs that only allow for collective attacks of at most k arguments.<\/jats:p>","DOI":"10.3233\/978-1-61499-906-5-49","type":"book-chapter","created":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T12:06:08Z","timestamp":1740053168000},"source":"Crossref","is-referenced-by-count":0,"title":["On the Expressive Power of Collective Attacks"],"prefix":"10.3233","author":[{"family":"Dvo&rcaron;&aacute;k Wolfgang","sequence":"additional","affiliation":[]},{"family":"Fandinno Jorge","sequence":"additional","affiliation":[]},{"family":"Woltran Stefan","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Computational Models of Argument"],"original-title":[],"deposited":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T12:21:24Z","timestamp":1740054084000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-905-8&spage=49&doi=10.3233\/978-1-61499-906-5-49"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-906-5-49","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2018]]}}}
