Circular critical exponents for Thue–Morse factors
Jeffrey O. Shallit, Ramin Zarifi · RAIRO - Theoretical Informatics and Applications · 2019
We prove various results about the largest exponent of a repetition in a factor of the Thue–Morse word, when that factor is considered as a circular word. Our results confirm and generalize previous results of Fitzpatrick and Aberkane & Currie.
