We consider random graphs built on a homogeneous Poisson point process on , , with points marked by i.i.d. random variables . Fixed a symmetric function , the vertexes of are given by points of the Poisson point process, while the edges are given by pairs with and . We call Poisson -generalized Boolean model, as one recovers the standard Poisson Boolean model by taking and . Under general conditions, we show that in the supercritical phase the maximal number of vertex-disjoint left–right crossings in a box of size is lower bounded by apart from an event of exponentially small probability. As special applications, when the marks are non-negative, we consider the Poisson Boolean model and its generalization to with , the weight-dependent random connection models with max-kernel and with min-kernel and the graph obtained from the Miller–Abrahams random resistor network in which only filaments with conductivity lower bounded by a fixed positive constant are kept.

我们考虑随机图 建立在齐次泊松点过程上 , ,含分 由iid随机变量标记 。修复了对称函数,的顶点 由泊松点过程的点给定,而边由对给出 和 和 。我们称之为 泊松 广义布尔模型,因为可以通过以下方法恢复标准的泊松布尔模型 和 。在一般条件下,我们表明,在超临界阶段,大小为1的盒子中顶点不相交的左右交点的最大数量 下界 除了几率很小的事件。作为特殊应用,当标记为非负数时,我们考虑使用Poisson布尔模型并将其推广为 和 ,具有最大内核和最小内核的与重量有关的随机连接模型,以及从Miller-Abrahams随机电阻器网络获得的图表,其中仅保留电导率较低且由固定正常数限制的灯丝。
