Roland Fraïssé (French: [ʁɔlɑ̃ fʁajse]; 12 March 1920 – 30 March 2008) was a French mathematical logician. Fraïssé received his doctoral degree from the University of Paris in 1953. In his thesis, Fraïssé used the back-and-forth method to determine whether two model-theoretic structures were elementarily equivalent. This method of determining elementary equivalence was later formulated as the Ehrenfeucht–Fraïssé game. Fraïssé worked primarily in relation theory. Another of his important works was the Fraïssé construction of a Fraïssé limit of finite structures. He also formulated Fraïssé's conjecture on order embeddings, and introduced the notion of compensor in the theory of posets.

rdfs:comment	Roland Fraïssé est un mathématicien (logicien) français, né le 12 mars 1920 à Bressuire (Deux-Sèvres) et mort le 30 mars 2008 dans le 8e arrondissement de Marseille. (fr) Roland Fraïssé (* 3. Dezember 1920; † 30. März 2008 in Marseille) war ein französischer mathematischer Logiker, der sich mit der Theorie der Relationen und Modelltheorie beschäftigte. Fraïssé wurde 1950 an der Universität Paris promoviert mit einer Arbeit, in der bereits Grundlagen für die von Andrzej Ehrenfeucht später weiterentwickelte Methode der Ehrenfeucht-Fraïssé-Spiele in der Modelltheorie gelegt wurden. Er war Professor an der Universität Lyon und ab 1991 an der Universität Marseille. (de) Roland Fraïssé (French: [ʁɔlɑ̃ fʁajse]; 12 March 1920 – 30 March 2008) was a French mathematical logician.

(en) Roland Fraïssé (francês: [ʁɔlɑ̃ fʁajse]; Bressuire, 12 de março de 1920 – Marselha, 30 de março de 2008) foi um lógico matemático francês. Fraïssé obteve um doutorado na Universidade de Paris em 1953. Em sua tese, Fraïssé usou o método do vai-e-vem (back-and-forth method) para determinar se duas estruturas de modelos teóricos são equivalentes elementares. Este método de determinar equivalência elementar foi depois formulado como jogo de Ehrenfeucht–Fraïssé. Fraïssé trabalhou primariamente com teoria das relações. Outro de seu trabalhos fundamentais foi a de um limite de Fraïssé de estruturas finitas. Ele também formulou a conjectura de Fraïssé sobre o embutimentos de ordem, e introduziu a noção de compensador em conjuntos parcialmente ordenados. (pt)
