Projections of four corner Cantor set: total self-similarity, spectrum and unique codings

Derong Kong, Beibei Sun

Given $ρ \in (0, 1/4]$ , the four corner Cantor set $E \subset R^{2}$ is a self-similar set generated by the iterated function system \[ \left\{(ρx, ρy), \quad(ρx, ρy+1-ρ),\qu…

Univoque bases of real numbers: simply normal bases, irregular bases and multiple rationals

Yu Hu, Yan Huang, Derong Kong

Given a positive integer $M$ and a real number $x \in (0, 1]$ , we call $q \in (1, M + 1]$ a univoque simply normal base of $x$ if there exists a unique simply normal sequence $(d_i)\in\{0,…

Rational Points in Translations of The Cantor Set

Kan Jiang, Derong Kong, Wenxia Li +1

Given two coprime integers $p \geq 2$ and $q \geq 3$ , let $D_{p} \subset [0, 1)$ consist of all rational numbers which have a finite $p$ -ary expansion, and let $$ K(q, \mathcal{A})=\bigg\{…

Intersections of middle- $α$ Cantor sets with a fixed translation

Yan Huang, Derong Kong

For $λ \in (0, 1/3]$ let $C_{λ}$ be the middle- $(1 - 2 λ)$ Cantor set in $R$ . Given $t \in [- 1, 1]$ , excluding the trivial case we show that \[ Λ(t):=\left\{λ\in(0,1/3]: C_λ\cap(C_λ+t…

On a class of self-similar sets which contain finitely many common points

Kan Jiang, Derong Kong, Wenxia Li +1

For $λ \in (0, 1/2]$ let $K_{λ} \subset R$ be a self-similar set generated by the iterated function system ${λ x, λ x + 1 - λ}$ . Given $x \in (0, 1/2)$ , let $Λ (x)$ be the set of $λ\in(0…

Critical values for the $β$ -transformation with a hole at $0$

Pieter Allaart, Derong Kong

Given $β \in (1, 2]$ , let $T_{β}$ be the $β$ -transformation on the unit circle $[0, 1)$ such that $T_{β} (x) = β x (mod 1)$ . For each $t \in [0, 1)$ let $K_{β} (t)$ be the survivor set consisting of…
