Let $(M^n,g)$ be a closed smooth Riemannian manifold. Consider a set $\mathcal B_{\epsilon}$ which is a maximal collection of points in $M$ with pairwise distance no smaller than $\epsilon$. We define the measure $$ m_{\epsilon}:=\frac{\sum_{x\in \mathcal B_{\epsilon}} \delta_{x}}{|B_{\epsilon}|}. $$ Can we prove that as $\epsilon \to 0$, $m_\epsilon$ converges weakly to the $n$-dimensional Hausdorff measure up to a rescaling?
