The critical random graph, with martingales

Probability 2011-11-10 v4 Combinatorics

Abstract

We give a short proof that the largest component of the random graph G(n,1/n)G(n, 1/n) is of size approximately n2/3n^{2/3}. The proof gives explicit bounds for the probability that the ratio is very large or very small.
