摘要:Fix an alphabet A={0,1,…,M}. The univoque set U of bases q in (1,M+1) in which the number 1 has a unique expansion over the alphabet A has been well studied. It has Lebesgue measure zero but Hausdorff dimension one. In this talk we will describe how the set U is distributed over the interval (1,M+1) by determining the local dimension of U. As an application we give a complete answer to a question of [P. Allaart, Adv. Math., 308:575--598, 2017] about strongly univoque sets. This is a joint work with Pieter Allaart.
