Roland Fraïssé (French: [ʁɔlɑ̃ fʁajse]; 12 March 1920 – 30 March 2008[1]) was a French mathematical logician.
Life
Fraïssé received his doctoral degree from the
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.[4]
Most of his career was spent as Professor at the University of Provence in Marseille, France.
