Abstract:We study the limit distribution of the volume fraction estimator $\widehat p_{\lambda, A}$ (= the Lebesgue measure of the intersection $\mathcal{X}\cap (\lambda A)$ of a random set $\mathcal{X}$ with a large observation set $\lambda A$, divided by the Lebesgue measure of $\lambda A$), as $\lambda \to \infty$, for a Boolean set $\mathcal{X}$ formed by uniformly scattered random grains $\Xi \subset \mathbb{R}^\nu$. We obtain general conditions on generic grain set $\Xi$ under which $\widehat p_{\lambda, A}$ has an $\alpha$-stable limit distribution with index $1 < \alpha \le 2$. A large class of Boolean models with randomly homothetic grains satisfying these conditions is introduced. We also discuss the limit distribution of the sample volume fraction of a Boolean set
observed on a large subset of a $\nu_0$-dimensional $(1 \le \nu_0 \le \nu -1$) hyperplane of $\mathbb{R}^\nu$.
