We characterize conjugation classes of Christoffel words (equivalently of standard words) by the number of factors. We give several geometric proofs of classical results on these words and sturmian words.
Mathematics Subject Classification: 68R15
Key words: Words / Christoffel / sturmian / conjugation / geometric.
