Palis' sumset conjecture for missing digits sets

About 3 years old · traced to

Let A,B⊂[0,1]A,B\subset[0,1] be missing digits sets. Palis' conjecture. Suppose that

dim⁡HA+dim⁡HB>1.\dim_{\mathrm{H}}A+\dim_{\mathrm{H}}B>1.

Then, generically, A+BA+B contains a non-trivial interval. In the paper's missing-digits setting, the source explains that genericity means that A+Tx(B)A+T_x(B) contains a non-trivial interval for Lebesgue almost every x∈Rx\in\mathbb{R}, where Tx(y)=xyT_x(y)=xy. The source notes that this is an informal version of Palis' conjecture and recalls stronger precise results in related dynamical settings.
