Abstract

We consider primitive aperiodic substitutions of constant length and prove that, in order to have a Lebesgue component in the spectrum of the associated dynamical system, it is necessary that one of the eigenvalues of the substitution matrix equals in absolute value. The proof is based on results of Queffélec combined with estimates of the local dimension of the spectral measure at zero.
