Sandpile models are a subclass of cellular automata. Bak et al. introduced them in 1987 for they exemplify the nicely named notion of “self-organized criticality”. Those non-linear discrete dynamical systems illustrate the evolution of cubic sand grains from nicely packed columns to nicely packed columns. A simple local rule is applied until reaching a stable configuration… It all looks very easy so far, but we will see that wonderful (and mysterious!) objects naturally appear. What can we understand about them? We will see some results on the emergence of regularities in one-dimensional sandpile models (joint work with Eric Rémila and Enrico Formenti).
