在$d$维的高密度元胞渗流模型包含一个表面,是同胚的$(d-1)$-球和封闭的起源。这是证明了一个路径计数参数的对偶模型。当$d=3$时,这允许在纠缠渗流的临界点$p_e$上有一个改进的下界,即$p_e\geq \mu^{-2}$,其中$\mu$是$\mathbb{Z}^3$上自避免行走的连接常数。此外,当边缘密度$p$低于这个界限时,包含原点的纠缠团簇的半径具有指数衰减的尾部。
The high-density plaquette percolation model in $d$ dimensions contains a surface that is homeomorphic to the $(d-1)$-sphere and encloses the origin. This is proved by a path-counting argument in a dual model. When $d=3$, this permits an improved lower bound on the critical point $p_e$ of entanglement percolation, namely $p_e\geq \mu^{-2}$ where $\mu$ is the connective constant for self-avoiding walks on $\mathbb{Z}^3$. Furthermore, when the edge density $p$ is below this bound, the radius of the entanglement cluster containing the origin has an exponentially decaying tail.
