Poisson超平面镶嵌中的多面单元

Cells with many facets in a Poisson hyperplane tessellation

Gilles Bonnet, Pierre Calka, Matthias Reitzner

摘要:

令$Z$是$\mathbb{R}^d$中静态泊松超平面细分的典型单元。研究了典型单胞的$f(Z)$面数分布。它表明,在一个良好的传播条件下的方向分布,数量$n^{\frac{2}{d-1}}\sqrt[n]{\mathbb{P}(f(Z)=n)}$是有界的,从上面和下面。当$f(Z)$较大时,$Z$的等周比以高概率远离零有界。这些结果依赖于一方面的互补定理,它提供了一个精确的分解分布的$Z$,另一方面在几个几何估计有关的近似多面体多面体与较少的方面。从$f(Z)$的分布的渐近性,尾部估计为所谓的$Φ$内容的$Z$的推导以及结果的条件分布的$Z$时,其$Φ$内容是大的。

英文摘要:

Let $Z$ be the typical cell of a stationary Poisson hyperplane tessellation in $\mathbb{R}^d$. The distribution of the number of facets $f(Z)$ of the typical cell is investigated. It is shown, that under a well-spread condition on the directional distribution, the quantity $n^{\frac{2}{d-1}}\sqrt[n]{\mathbb{P}(f(Z)=n)}$ is bounded from above and from below. When $f(Z)$ is large, the isoperimetric ratio of $Z$ is bounded away from zero with high probability. These results rely on one hand on the Complementary Theorem which provides a precise decomposition of the distribution of $Z$ and on the other hand on several geometric estimates related to the approximation of polytopes by polytopes with fewer facets. From the asymptotics of the distribution of $f(Z)$, tail estimates for the so-called $Φ$ content of $Z$ are derived as well as results on the conditional distribution of $Z$ when its $Φ$ content is large.
