Abstract: The essential boundary of a measurable set is related to the de Giorgi perimeter and was introduced by Vol'pert in his "improvement" of Federer's work.

For a totally disconnected compact set of positive measure in $ n$ space the essential boundary can be of Hausdorff $ n - 1$ dimension but cannot have $ \sigma $ finite $ (n - 1)$-measure.
