Title
Connectivity in bridge-addable graph classes: The McDiarmid–Steger–Welsh conjecture
Abstract
A class of graphs is bridge-addable if given a graph G in the class, any graph obtained by adding an edge between two connected components of G is also in the class. We prove a conjecture of McDiarmid, Steger, and Welsh, that says that if Gn is any bridge-addable class of graphs on n vertices, and Gn is taken uniformly at random from Gn, then Gn is connected with probability at least e−12+o(1), when n tends to infinity. This lower bound is asymptotically best possible since it is reached for forests.
