Let be a graph chosen uniformly at random from the class of all planar graphs on vertex set with edges. We show that in the sparse regime, when , with high probability the maximum degree of takes at most two different values. In contrast, this is not true anymore in the dense regime, when , where the maximum degree of is not concentrated on any subset of with bounded size.

随机平面图中最大度数的集中
让是从顶点集上所有平面图的类中均匀随机选择的一个图和边缘。我们证明了在稀疏状态下,当, 最大程度的概率很高最多取两个不同的值。相反,这在稠密体制中不再正确,当, 其中最大程度不集中在任何子集上有界的大小。
