Topological and dimensional properties of univoque bases in double-base expansions

Yuecai Hu, Rafael Alcaraz Barrera, Yuru Zou

Given two real numbers $q_0,q_1$ with $q_0,q_1>1$ satisfying $q_0+q_1\ge q_0{q}_1$, we call a sequence $(d_i)$ with $d_i\in \{0,1\}$ a $(q_0,q_1)$-expansion or a double-base expa…
