    Asymptotic repetitive threshold of balanced sequences

  • Original language description

    The critical exponent E(u) of an infinite sequence u over a finite alphabet expresses the maximal repetition of a factor in u. By the famous Dejean's theorem, E(u) is less or equal to 1+1/(d-1) for every d-ary sequence u. We define the asymptotic critical exponent E*(u) as the upper limit of the maximal repetition of factors of length n. We show that for any d>1 there exists a d-ary sequence u having E*(u) arbitrarily close to 1. Then we focus on the class of d-ary balanced sequences. In this class, the values E*(u)$ are bounded from below by a threshold strictly bigger than 1. We provide a method which enables us to find a d-ary balanced sequence with the least asymptotic critical exponent for 1<d<11.
