BALANCE PROPERTIES OF ARNOUX–RAUZY WORDS
Abstract
This paper deals with balances and imbalances in Arnoux–Rauzy words. We provide sufficient conditions for C-balancedness, but our results indicate that even a characterization of 2-balanced Arnoux–Rauzy words on a 3-letter alphabet is not immediate.
