Abstract

We show that the diameter diam(Gn ) of a random labelled connected planar graph with n vertices is equal to n1/4+o(1) , in probability. More precisely, there exists a constant c > 0 such that

$$P(\D(G_n)\in(n^{1/4-\e},n^{1/4+\e}))\geq 1-\exp(-n^{c\e})$$
for ε small enough and n ≥ n0(ε). We prove similar statements for 2-connected and 3-connected planar graphs and maps.
