... complexity of the characteristic function of A. Forfixeds, t ∈>0, define the characteristic function of A as χ = χ (A) :>0−→ {0, 1},whereχ(x)=1,x∈ A 0,x/∈ A. Awordw is a factor of y if there ... motivates the question of whether A has a similar property when s ≥ 2. Perhaps associated with some of the A sequences for s ≥ 2 is an integer m ≥ 2 such that for all i, j, k, | (A k+i A k)− (A j+i A j)|≤m.Another ... this area, we refer the reader to [2] and [8]. In particular, [13] contains an analysis of the subword complexity of infinite sequences S of the form S = fω(b), where f is a morphism such that...
