A shape theorem for exploding sandpiles

Probability 2023-05-03 v2 Analysis of PDEs Combinatorics

Abstract

We study scaling limits of exploding Abelian sandpiles using ideas from percolation and front propagation in random media. We establish sufficient conditions under which a limit shape exists and show via a family of counterexamples that convergence may not occur in general. A corollary of our proof is a simple criteria for determining if a sandpile is explosive; this strengthens a result of Fey, Levine, and Peres (2010).
