New dimension bounds for $αβ$ sets
In this paper we obtain new lower bounds for the upper box dimension of $\alpha\beta$ sets. As a corollary of our main result, we show that if $\alpha$ is not a Liouville number and $\beta$ is a Liouville number, then the upper box dimension of any $\alpha\beta$ set is $1$. We also use our dimension bounds to obtain new results on affine embeddings of self-similar sets.
