Jeff Kahn, Rutgers University, USA

Abstract

We disprove a conjecture of Russ Lyons---that for every locally finite, connected graph G, the critical probability for (Bernoulli bond) percolation on G is equal to the "first moment method" lower bound on this probability---and propose a possible alternative.
