面循环渗流

Face and cycle percolation

Christian Hirsch, Daniel Valesin

摘要:

我们考虑面和循环渗流模型的连续渗流的基础上随机单纯复形在欧几里得空间。面渗流是通过共享一个$(d-1)$维面的$d$ -单形的无穷序列来定义的.相比之下,循环渗流要求存在无限的$d$ -循环,从而推广了格元渗流的概念。我们讨论了表面渗流的急剧相变,并得出表面渗流和循环渗流的临界强度之间的比较结果。最后,我们考虑一个替代版本的单纯形渗透,通过宣布单纯形是邻居,只要他们足够接近对方,并证明了一个严格的不等式,涉及的临界强度的替代版本和面对渗透。

英文摘要:

We consider face and cycle percolation as models for continuum percolation based on random simplicial complexes in Euclidean space. Face percolation is defined through infinite sequences of $d$-simplices sharing a $(d-1)$-dimensional face. In contrast, cycle percolation demands the existence of infinite $d$-cycles, thereby generalizing the lattice notion of plaquette percolation. We discuss the sharp phase transition for face percolation and derive comparison results between the critical intensities for face and cycle percolation. Finally, we consider an alternate version of simplex percolation, by declaring simplices to be neighbors whenever they are sufficiently close to each other, and prove a strict inequality involving the critical intensity of this alternate version and that of face percolation.
