Probability Seminar: Supercritical percolation on finite transitive graphs

Topic: 
Supercritical percolation on finite transitive graphs
Monday, February 22, 2021 - 11:00am

Tom Hutchcroft (Cambridge)
Abstract / Description: 

In Bernoulli bond percolation, each edge of some graph are chosen to be either deleted or retained independently at random with retention probability p. For many large finite graphs, there is a phase transition such that if p is sufficiently large then there exists a giant cluster whose volume is proportional to that of the graph with high probability. We prove that in this phase the giant cluster must be unique with high probability: this was previously known only for tori and expander graphs via methods specific to those cases. The work that I will describe is joint with Philip Easo.
