Title: Percolation and cellular automata
Abstract: Given an infinite graph G and $p \in [0,1]$, we say that G percolates with parameter p if the random subgraph obtained by removing each edge with probability 1-p is almost surely infinite. I will give a simple introduction to the theory of percolation on Cayley graphs of finitely generated groups and use it to present a nice application to the theory of celullar automata. Based on joint work with Felipe García-Ramos and Siamak Taati.
