Abstract:
If you start with an infinite network and then cut some of the connections at random, how connected is the resulting network? It turns out that the answer is “very” or “not very much at all,” and this gives one of the prototypical examples of a phase transition in statistical physics. I’ll explain what percolation is, what it means that it has a phase transition, and hopefully a little bit about Hugo Duminil-Copin and Vincent Tassion’s relatively recent very nice proof of the “sharpness” of the phase transition.Date: Friday, September 23, 2022
