Let $\mu_{\rho,d}$ be the Bernoulli convolution with contraction parameter $0<\rho\le1/2$ and scale parameter $d>0$. A measure is spectral when its associated $L^2$ space admits an…

Let $(N_j,B_j)$ be the almost-Parseval-frame tower defined in Theorem 0.1, and let $bc$ be its associated measure. The measure $bc$ is spectral if there exists a set…
