Abstract
AbstractWe introduce and investigate superdensity and the density degree of sets with respect to a Radon measure on $${\mathbb {R}}^n$$
R
n
. Some applications are provided. In particular, we prove a result on the approximability of a set by closed subsets of small density degree and a generalization of Schwarz’s theorem on cross derivatives.
