The goal of this mini-course will be to introduce the basic methods of combinatorics on words. The topics will cover finite and infinite words, Sturmian words, patterns, codes, noncommutative series and polynomials. Lectures will be given by leading researchers in the field. Tentatively **Jean Berstel** and** ****Christophe Reutenauer**.

#### Centre de recherches mathématiques

**Scientific organizers**: *S. Brlek* (UQAM), *C. Reutenauer* (UQAM) and *B. Sagan* (Michigan State)

This workshop will include expository talks as well as presentations on current research highlighting the flow of ideas between combinatorics on words and several other fields of mathematics and theoretical computer science. In particular, we want to stress combinatorial, algebraic and algorithmic aspects, while underlying the manifold interactions with other fields, and particularly Number Theory, Theoretical Computer Science and Algebra.
