Abstract

For any x ∈ (0, 1], let x = 1 d1 + 1 d1(d1 − 1)d2 + ⋯ + 1 d1(d1 − 1)⋯dn−1(dn−1 − 1)dn + ⋯ be its Lüroth expansion with digits {dj ≥ 2,j ≥ 1}. Let ψ : ℕ → ℠+ be a function satisfying ψ(n)/n →∞ as n →∞ and E(ψ) := x ∈ (0, 1] :limn→∞ 1 ψ(n)∑j=1nlog d j(x) = 1 . In this paper, we give the Hausdorff dimension of the set E(ψ) without any extra condition on ψ. This result extends the former work of the first author (Fractals 28(4) (2020) 2050064, doi:10.1142/S0218348X20500644).
