Can you give an example for a finite dimension n why Borel-sets aren't measurable under the $delta$-approximative d-dimensional Hausdorff measure? (as defined here: https://en.wikipedia.org/wiki/Hausdorff_measure#Definition) Thus my question is about an example-Borel-set with this feature.

  • Might someone explain which information you need in addition. We showed it only for $mathbbR^2$ so that I don't know whether this works in higher dimensions. Shall I add this?
