Circular critical exponents for Thue-Morse factors (1808.02529v1)
Published 7 Aug 2018 in cs.FL, cs.DM, and math.CO
Abstract: 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.
