Adam Timar

AI总结:

针对维度$d≥3$的欧几里得空间中两个独立单位强度泊松点过程,构造了等变可测的因子完美匹配,其配对距离尾部分布以$b\textrm{exp}(-cr^d)$快速衰减,证明依赖于泊松点过程的类似尾部分配规则和分数完美匹配转完美匹配的定理。

摘要:

考虑二维欧几里得空间中强度为1的两个独立泊松点过程,其中维度$d$至少为3。我们构造了两个点集之间的完美匹配,该匹配是一个因子(即点配置的等变可测函数),且具有以下性质:配置点与其配对点之间的距离的尾部分布衰减速度尽可能快,即具有合适常数$b,c>0$的$b\textrm{exp}(-cr^d)$形式。我们的证明依赖于两个早期结果:泊松点过程的类似尾部分配规则,以及最近的一个定理,该定理使我们能够从分数完美匹配中获得完美匹配。

英文摘要:

Consider two independent Poisson point processes of unit intensity in the Euclidean space of dimension $d$ at least 3. We construct a perfect matching between the two point sets that is a factor (i.e., an equivariant measurable function of the point configurations), and with the property that the distance between a configuration point and its pair has a tail distribution that decays as fast as possible, namely, as $b\exp (-cr^d)$ with suitable constants $b,c>0$. Our proof relies on two earlier results: an allocation rule of similar tail for a Poisson point process, and a recent theorem that enables one to obtain perfect matchings from fractional perfect matchings in our setup.
