Title: The arboreal gas
Abstract: In Bernoulli bond percolation each edge of a graph is declared open with probability p, and closed otherwise, and one typically asks questions about the random subgraph of open edges. The arboreal gas is the probability measure obtained by conditioning on the event that the percolation subgraph is a forest, i.e., contains no cycles.
What are the percolative properties of these random forests? Do they contain giant trees? I will discuss what is known and conjectured.
Based on joint work with R. Bauerschmidt, N. Crawford, and A. Swan.
The talk will be followed by refreshments in the Huxley Common Room at 4pm.
