摘要

We study natural measures on sets of beta-expansions and on slices through self-similar sets. In the setting of beta-expansions, these allow us to better understand the measure of maximal entropy for the random beta-transformation and to reinterpret a result of Lindenstrauss, Peres and Schlag in terms of equidistribution. Each of these applications is relevant to the study of Bernoulli convolutions. In the fractal setting this allows us to understand how to disintegrate Hausdorff measure by slicing, leading to conditions under which almost every slice through a self-similar set has positive Hausdorff measure, generalising long known results about almost everywhere values of the Hausdorff dimension.
