Metric results for dyadic approximation on the middle-third Cantor set

Xin-Rong Dai, Bing Li, Bo Wang +1

Let $C$ be the middle-third Cantor set and $μ$ be the Cantor-Lebesgue measure on $C$ . A conjecture of Velani states that $μ (W_{2} (τ)) = 0$ if $τ > 1$ and $μ (W_{2} (τ)) = 1$ if $0 < τ \leq 1$ , wh…

Intersecting well approximable and missing digit sets

Bing Li, Sanju Velani, Bo Wang

Let $b \geq 3$ be an integer and $C (b, D)$ be the set of real numbers in $[0, 1]$ whose $b$ -ary expansion consists of digits restricted to a given set $D \subseteq {0, \dots, b - 1}$ . Giv…

A winning approach to the intersections of twisted non-recurrent sets with fractals

Junjie Huang, Bing Li, Bo Wang +1

In this paper, we prove that if $S \subseteq R^{d}$ is hyperplane absolute winning on a closed hyperplane diffuse set $L \subseteq R^{d}$ , then $\mathrm{dim}_H S\cap K=\m…

Ramírez's problems and fibers on well approximable set of systems of affine forms

Bing Li, Bo Wang

We show that badly approximable matrices are exactly those that, for any inhomogeneous parameter, can not be inhomogeneous approximated at every monotone divergent rate, which gene…

Metric results for the eventually always hitting points and level sets in subshift with specification

Bo Wang, Bing Li

We study the set of eventually always hitting points for symbolic dynamics with specification. The measure and Hausdorff dimension of such sets are obtained. Moreover, we establish…

Uniform Diophantine approximation with restricted denominators

Bo Wang, Bing Li, Ruofan Li

Let $b \geq 2$ be an integer and $A = (a_{n})_{n = 1}^{\infty}$ be a strictly increasing subsequence of positive integers with $η:=\limsup\limits_{n\to\infty}\frac{a_{n+1}}{a_{n}}<+\inft…
