Abstract

We prove that if μ is a Radon measure on the Heisenberg group Hn such that the density θ sμ), computed with respect to the Korányi metric dH, exists and is positive and finite on a set of positive μ measure, then s is an integer. The proof relies on an analysis of uniformly distributed measures on Hn, dH. We provide a number of examples of such measures, illustrating both the similarities and the striking differences of this sub-Riemannian setting from its Euclidean counterpart.
