关于平面Poisson线过程的面积和周长的分布函数

On the Distribution function of area and perimeter for planar poisson line process

摘要:

在几何变换理论中,检验空间的随机划分的挑战是一类重要的问题。理查德·迈尔斯在1972年计算了空间随机划分的任意阶(包括期望)的面积和周长的矩。本文用泊松线过程计算平面随机剖分的全分布函数。其思想是将随机多边形解释为沿移动直线的线段的演化。在平面例子中,通过考虑割线克服了与无穷多个参数有关的问题。我们将考虑以下任务:{ \textbf 1.}在平面上,提供了一随机集直线,所有的移位都是同样可能的,分布规律的形式是$F(φ).$分区的组件的面积分布是什么?{ \textbf 2.}在平面上,标记了点的随机集。每个点$A$都有一个相关的吸引区域,该区域是平面上的点的集合,其中点$A$是指定点中最接近的点。在第一个问题中,邻近线的移动部分的密度允许以动力学形式表达平衡比。同样,你可以写出周长的运动方程。本文将演示如何使用拉普拉斯变换将这些方程约化为黎卡提方程。

英文摘要:

The challenges of examining random partitions of space are a significant class of problems in the theory of geometric transformations. Richard Miles calculated moments of areas and perimeters of any order (including expectation) of the random division of space in 1972. In the paper we calculate whole distribution function of random divisions of plane by poisson line process. The idea is to interpret a random polygon as the evolution of a segment along a moving straight line. In the plane example, the issue connected with an infinite number of parameters is overcome by considering a secant line. We shall take into account the following tasks: {\textbf 1.} On the plane, a random set of straight lines is provided, all shifts are equally likely, and the distribution law is of the form $F(φ).$ What is the area distribution of the partition's components? {\textbf 2.} On the plane, a random set of points is marked. Each point $A$ has an associated area of attraction, which is the collection of points in the plane to which the point $A$ is the nearest of the designated ones. In the first problem, the density of moved sections adjacent to the line allows for the expression of the balancing ratio in kinetic form. Similarly, you can write the perimeters kinetic equations. We will demonstrate how to reduce these equations to the Riccati equation using the Laplace transformation in this paper.
