Limit values of the recurrence quotient of Sturmian sequences. (English) Zbl 0916.68115
Summary: The recurrence quotient is a real number associated to any symbolic sequence. In the case of Sturmian sequences, Morse and Hedlund proved that the smallest possible value is \((5+5)/2\). We study here the structure of the set of values taken by the recurrence quotient for a Sturmian sequence.
