摘要

Let {A_k}_k=1^∞ be a sequence of finite subsets of R^d satisfying that #A_k≥2 for all integers k≥1. In this paper, we first give a sufficient and necessary condition for the existence of the infinite convolution ν=δ_A₁⁎δ_A₂⁎⋯⁎δ_{A_n}⁎⋯, where all sets A_k⊆R₊^d and [Formula presented]. Then we study the spectrality of a class of infinite convolutions generated by Hadamard triples in R and construct a class of singular spectral measures without compact support. Finally we show that such measures are abundant, and the dimension of their supports has the intermediate-value property.
