The Evolution of Uniform Random Planar Graphs

Chris Dowden


Let $P_{n,m}$ denote the graph taken uniformly at random from the set of all planar graphs on $\{1,2, \ldots, n \}$ with exactly $m(n)$ edges. We use counting arguments to investigate the probability that $P_{n,m}$ will contain given components and subgraphs, finding that there is different asymptotic behaviour depending on the ratio ${m\over n}$.
