Fran\u00e7ois Lucas est mort le 25 avril 2016, apr\u00e8s des ann\u00e9es d\u2019un combat courageux et intense contre la maladie. Il avait \u00e9t\u00e9 l\u2019un des tout premiers membres du groupe de logique parisien, dans les ann\u00e9es 70. Il aura \u00e9t\u00e9 jusqu\u2019\u00e0 la fin un auditeur et un intervenant assidu du S\u00e9minaire sur les Structures Alg\u00e9briques Ordonn\u00e9s. Tout en continuant d\u2019apporter des contributions r\u00e9guli\u00e8res \u00e0 la th\u00e9orie des mod\u00e8les des structures ordonn\u00e9es, il avait d\u00e9velopp\u00e9 d\u2019autres th\u00e8mes de recherche importants. Il faut en particulier signaler sa collaboration avec James Madden, Daniel Schaub et Mark Spivakovski sur la conjecture de Pierce-Birkhoff. Un volume en son honneur<\/u><\/a> a \u00e9t\u00e9 publi\u00e9 aux Annales de la Facult\u00e9 des Sciences de Toulouse en 2012, dont l\u2019introduction donne un compte-rendu plus d\u00e9taill\u00e9 de ses travaux. Tr\u00e8s dynamique et chaleureux, Fran\u00e7ois a \u00e9t\u00e9 co-organisateur de nombreuses rencontres scientifiques au CIRM et \u00e0 Angers. C\u2019\u00e9tait un militant syndical engag\u00e9 qui a repr\u00e9sent\u00e9 les math\u00e9maticiens au CNU. Il \u00e9tait plus g\u00e9n\u00e9ralement un citoyen du monde, tr\u00e8s actif dans le milieu associatif. Sa curiosit\u00e9 intellectuelle et sa passion pour les arts \u00e9taient immenses. Il pratiquait lui-m\u00eame la gravure, il avait cr\u00e9\u00e9 et animait une association permettant d\u2019exercer cet art.<\/p>\n\n\n\n
