Abstract
Let β∈(0,1) be an irrational, and [a 1,a 2,...] be the continued fraction expansion of β. Let H β be the one-dimensional Schrödinger operator with Sturmian potentials. We show that if the potential strength V>20, then the Hausdorff dimension of the spectrum σ(H β) is strictly great than zero for any irrational β, and is strictly less than 1 if and only if lim inf k→∞(a 1 a 2⋅⋅⋅a k ))1/k<∞.
