We define the notion of circular words, then consider on such words a constraint derived
from the Fibonacci condition. We give several results on the structure of these circular words,
then mention possible applications to various situations: periodic expansion of numbers in
numeration systems," gcd-property" of integer sequences, partition of the prefix of the fixed
point of the Fibonacci substitution, spanning trees of a wheel. Eventually, we mention some
open questions.
