Discrete Harmonic Analysis and the Divisible Sandpile

In the recent paper "Strong Spherical Asymptotics for Rotor-Router Aggregation and the Divisible Sandpile" by L. Levine and Y. Peres the authors prove shape results about a number of deterministic growth models, one of them being the Divisible Sandpile. The key idea in their paper is the rather surprising technique of applying the discrete equivalent of harmonic analysis to this almost combinatorial problem. In this talk I will introduce the Divisible Sandpile model and Discrete Harmonic Analysis, and describe how the latter can be applied to prove an important lemma about the former.
