Title: Avoiding rational distances
We shall present results obtained by Ashutosh Kumar in paper “Avoiding rational distances”. The author showed that for any set of reals X of positive outer measure there exists a subset Y of X such that Y has the same outer measure and the distance between any distinct points of Y is irrational.
We will also discuss briefly the case of higher dimensions.
