On the Invariant Density of the Random Beta-Transformation
arXiv:1303.1081
Abstract
We construct a Lebesgue measure preserving natural extension of the random beta-transformation. This allows us to give a formula for the density of the absolutely continuous invariant probability measure, answering a question of Dajani and de Vries, and also to evaluate some estimates on the typical branching rate of the set of beta-expansions of a real number.
