Dec 22, 2023 at 13:47 | comment | added | Zach Teitler | Yes. arxiv.org/abs/1711.08791, "Cantor Set Arithmetic" by Athreya, Reznick, and Tyson, in the Monthly in 2019: every element in $[0,1]$ can be written as $x^2y$ for some Cantor set elements $x,y$. | |
Dec 22, 2023 at 13:42 | comment | added | Will Brian | Hmm. I could be wrong, but it looks like the numbers that are products of $2$ members of the Cantor set should be a closed nowhere dense subset of $[0,1]$. If this were true for all $n \geq 2$, then you'd have your answer. | |
Dec 22, 2023 at 13:32 | comment | added | Joel David Hamkins | I'd suggest "every" in place of "any" in your title and questions. The word "any" is famously ambiguous between $\exists$ and $\forall$. In questions especially, it often seems more to carry the $\exists$ meaning, such as in "Was any student able to solve the problem?" or "Is any doctor on the plane?". But I believe you want the $\forall$ meaning. | |
