Titre / Title: Semigroups and automata on infinite words
Abstract : This paper is an introduction to the algebraic theory of infinite words. It emphasizes the combinatorial and algebraic aspects of this theory and is written with the perspective of generalizing the results on recognizable sets of finite words to infinite words. The equivalence between Büchi automata and Muller automata is first presented. Then the theory of semigroups recognizing sets of finite words is extended to infinite words. The analogy with the theory for finite words is pushed sufficiently far to obtain a counterpart of Eilenberg's variety theorem for finite or infinite words.
