- Description
- Let β> 1 be a real number and define the β-transformation on [0,1] by Tβ : x ↦ βx mod 1. Further, define: [formula could not be replicated] and [formula could not be replicated], where Ψ : ℕ → ℝ>0 is a positive function such that Ψ(n) → 0 as n → ∞. In this paper, we show that each of the above sets obeys a Jarník-type dichotomy, that is, the generalized Hausdorff measure is either zero or full depending upon the convergence or divergence of a certain series. This work completes the metrical theory of these sets.
