摘要
我们研究了偶数个顶点的随机立方平面图 C n $\mathsf {C}_n$。我们证明,当 n ∈ 2 N $n \in 2 \mathbb {N}$趋于无穷大时,布朗映射作为 C n $mathsf {C}_n$ 的格罗莫夫-豪斯多夫-普罗霍罗夫缩放极限而出现,在对特定常数 γ > 0 $\gamma >0$ 对距离进行 γ n - 1 / 4 $\gamma n^{-1/4}$ 重缩放之后。这是首次证明未嵌入平面的随机图模型收敛于布朗图。我们的方法采用了一种新方法,使我们能够将随机图上的距离与它们的 3 连接核心上的第一通道渗流距离联系起来。
We study the random cubic planar graph with an even number of vertices. We show that the Brownian map arises as Gromov–Hausdorff–Prokhorov scaling limit of as tends to infinity, after rescaling distances by for a specific constant . This is the first time a model of random graphs that are not embedded into the plane is shown to converge to the Brownian map. Our approach features a new method that allows us to relate distances on random graphs to first-passage percolation distances on their 3-connected core.
