Percolation for the stable marriage of Poisson and Lebesgue

英文摘要：

Let $Ξ$ be the set of points (we call the elements of $Ξ$ centers) of Poisson process in $\R^d$, $d\geq 2$, with unit intensity. Consider the allocation of $\R^d$ to $Ξ$ which is stable in the sense of Gale-Shapley marriage problem and in which each center claims a region of volume $α\leq 1$. We prove that there is no percolation in the set of claimed sites if $α$ is small enough, and that, for high dimensions, there is percolation in the set of claimed sites if $α<1$ is large enough.
