I would like to talk about the zero-temperature Glauber dynamics of
a random-field Ising model on Bethe lattices. With a special initial condition,
we can exactly derive a macroscopically closed evolution equation,
which determines a dynamical phase diagram related to avalanche phenomena.
I will mention a possible application of this analysis for epidemic networks.
