Random Bernoulli measures in a random environment

Abstract

We study random Bernoulli measures ${\mu }_{\mathbf{p}}$ in a random environment $\mathbf{p}=(p_1,p_2,\dots )$, where $p_n$ are independent and identically distributed on $(0,1)$. For almost every environment $\mathbf{p}$, we establish several almost sure properties of ${\mu }_{\mathbf{p}}$: its local dimension, $L^q$ dimensions, Rajchman property, mutual singularity with any fixed measure, and a dichotomy for normal numbers of its typical points.
