The authors consider integral self-affine spectral measures, such that the zeros of their Fourier transform are all integral vectors; and they prove that their spectrum has a tree structure. They also study the above problem relative to subsets, and obtain nice characterizations as well. Applications to known cases accomplish the paper.
