Sur le monoide syntactique de L∗ lorsque L est un langage fini
TL;DR: Nous montrons que pour chaque monoide fini M, il existe un langage fini L tel que M divise le monoide syntactique de L*.
Book ChapterDOI
The Expressive Power of Existential First Order Sentences of Büchi's Sequential Calculus
TL;DR: This paper completes the study of the hierarchy based on quantifier alternations (or ∑n-hierarchy), and gives a semigroup theoretic description of the expressive power of ∑1, the existential formulas, and s∑2, the boolean combinations of existential formulas.
Journal ArticleDOI
Ordered categories and ordered semigroups
TL;DR: In this paper, ordered categories were used to study semidirect decompositions of finite ordered semigroups, and they obtained ordered analogues of the derived semigroupoid theorem and of the delay theorem.
Book ChapterDOI
Positive Varieties and Infinite Words
TL;DR: A counterpart of Eilenberg's variety theorem for finite and infinite words is obtained and a purely algebraic characterization of various classes of recognizable sets defined by topological properties or by combinatorial properties is given.
