Hyperbolic Lifts and Estimates for Overlap Numbers

  • Eugen MihailescuEmail author


We first compute topological overlap numbers in several concrete cases. In particular is obtained a class of Bernoulli convolutions systems which asymptotically are irrational-to-1 on their limit sets. Next, for general conformal iterated function systems and for a class of potentials \(\psi \), we prove an estimate on the box dimension of a measure \(\nu _\psi \) on the limit set, associated to an equilibrium measure \(\mu _\psi \) on the respective hyperbolic lift. Also we study the structure of the families of conditional measures of \(\mu _\psi \) with respect to various fiber partitions, and find relations between them.
