Caio T. M. Alves, Marcelo Hilário, Bernardo N. B. de Lima, Daniel Valesin

摘要:

本文研究了具有点集$\mathbb{Z}^d \times \mathbb{Z}_+$和定向边为$\langle (x,t), (x+y,t+1)\rangle$的图上的定向长程渗流,其中$x,y$为$\mathbb{Z}^d$和$t \in \mathbb{Z}_+$中的定向长程渗流.这种形式的任何边都以概率$p_y$开放,对所有边都是独立的。假设值$p_y$在无穷大不为零,我们表明,有渗流,即使所有的边缘长度超过$k$删除,$k$足够大。我们还陈述了在$\mathbb{Z}^d$上长程接触过程的类似结果。

英文摘要:

We consider oriented long-range percolation on a graph with vertex set $\mathbb{Z}^d \times \mathbb{Z}_+$ and directed edges of the form $\langle (x,t), (x+y,t+1)\rangle$, for $x,y$ in $\mathbb{Z}^d$ and $t \in \mathbb{Z}_+$. Any edge of this form is open with probability $p_y$, independently for all edges. Under the assumption that the values $p_y$ do not vanish at infinity, we show that there is percolation even if all edges of length more than $k$ are deleted, for $k$ large enough. We also state the analogous result for a long-range contact process on $\mathbb{Z}^d$.
