This idea tries to represent the orderings in the simplest manner, avoiding any unnecessary information. For this purpose, the new concept of representability is developed by means of partial functions, so that other common definitions of representability (i.e. (Richter-Peleg) multi-utility, Scott-Suppes representability, \u2026 ) are now particular cases in which the partial functions are actually functions. The paper also presents a collection of examples and propositions showing the advantages of this kind of representations, particularly in the case of partial orders and semiorders, as well as some results showing the connections between distinct kinds of representations. <\/jats:p>","DOI":"10.1142\/s0218488518500228","type":"journal-article","created":{"date-parts":[[2018,5,9]],"date-time":"2018-05-09T04:06:40Z","timestamp":1525838800000},"page":"453-473","source":"Crossref","is-referenced-by-count":7,"title":["Partial Representations of Orderings"],"prefix":"10.1142","volume":"26","author":[{"given":"G.","family":"Bosi","sequence":"first","affiliation":[{"name":"Dipartimento de Scienze Economiche, Aziendali, Mathematiche e Statistiche, Universit\u00e0 degli Studi di Trieste, Piazzale Europa 1, I-34127, Trieste, Italia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8822-2438","authenticated-orcid":false,"given":"A.","family":"Estevan","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1ticas, Universidad P\u00fablica de Navarra, Campus Arrosad\u00eda, Pamplona, 31006, Spain"}]},{"given":"M.","family":"Zuanon","sequence":"additional","affiliation":[{"name":"Dipartimento di Economia e Management, Universit\u00e0 degli Studi di Brescia, Contrada Santa Chiara 50, 25122 Brescia, Italy"}]}],"member":"219","published-online":{"date-parts":[[2018,5,30]]},"reference":[{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmp.2006.10.005"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1142\/s0218488515500142"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.mathsocsci.2015.10.006"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmp.2013.01.003"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.2307\/2525513"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1007\/s11083-015-9360-1"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1007\/s11083-012-9255-3"},{"key":"p_14","doi-asserted-by":"publisher","DOI":"10.1142\/S0218488513500323"},{"key":"p_16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmateco.2011.07.003"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.1287\/opre.18.2.207"},{"key":"p_20","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2005.10.015"},{"issue":"7","key":"p_21","first-page":"558","volume":"21","author":"Lamport L.","journal-title":"ACM Commun.
