Titre / Title: On embeddings of finitely generated profinite semigroups into 2- generated profinite semigroups
Abstract : Koryakov recently asked following question : when a pseudo-variety V does not satisfy any non-trivial identity, does there exist an embedding from any finitely generated V-free profinite semigroup into the 2-generated V-free profinite semigroup? During the conference Semigroups, Automata and Languages in Porto (June 1994), a positive answer to this question was conjectured. We give here a counter example to this conjecture.
