Title: Uncomputability in bootstrap percolation


I will present a proof that the critical probabilities of supercritical two-dimensional bootstrap percolation models are, in general, uncomputable. I will also explain what all this means, and I'll present a d-dimensional generalization.

This is joint work with Paul Balister, Bela Bollobas and Rob Morris.
