On the probability of planarity of a random graph near the critical point
2014
Proceedings of the American Mathematical Society
Erdős and Rényi conjectured in 1960 that the limiting probability p that a random graph with n vertices and M = n/2 edges is planar exists. It has been shown that indeed p exists and is a constant strictly between 0 and 1. In this paper we answer completely this long standing question by finding an exact expression for this probability, whose approximate value turns out to be p ≈ 0.99780. More generally, we compute the probability of planarity at the critical window of width n 2/3 around the
