Abstract: We consider symbolic flows over finite alphabets and study certain kinds of repetitions in these sequences. Positive and negative results for the existence of such repetitions are given for codings of interval exchange transformations and codings of quadratic polynomials.
Keywords: symbolic flows, subshifts, repetitions, powers, interval
