自对偶平面超图与精确键逾渗阈值

Self-dual planar hypergraphs and exact bond percolation thresholds

J. C. Wierman, R. M. Ziff

摘要:

最近对逾渗的研究已经导致了一个无限类的格的构造,其中的逾渗阈值可以被精确地确定。我们讨论了债券渗流模型的解决方案的数学基础,特别是,试图解决一些误解,可能会出现的开创性文章齐夫和Scullard。作为一个结果,我们表明,存在无穷多个实数$a \in [0,1]$,其中有无穷多个晶格的键渗流阈值等于$a$。

英文摘要:

Recent research on percolation has led to the construction of an infinite class of lattices for which the percolation thresholds can be determined exactly. We discuss the mathematical basis for the solutions of bond percolation models, and, in particular, attempt to address some misconceptions that might arise from the seminal articles by Ziff and Scullard. As one consequence, we show that there exist infinitely many real numbers $a \in [0,1]$ for which there are infinitely many lattices that have bond percolation threshold equal to $a$.
