Geometric & Combinatorial Group Theory Seminar

Christophe Reutenauer, UQAM. Christoffel words are a finitary version of sturmian sequences. They are related to continued fractions, discretization of lines in the plane and to combinatorics on words and palindromes. We give some elements of this theory, by stressing the geometric approach.
