 Abstract: Originating in statistical physics and nearly simultaneously
and independently introduced in algebraic graph theory and
in theoretical computer science in the 1990s, the Abelian
Sandpile Model associates a variety of structures with
a diffusion process on finite graphs.  The model gives rise
to a remarkably rich theory which connects the fields of graph
theory, stochastic processes, commutative semigroups and
groups, matrices and determinants, lattices in n-dimensional
space, algorithms, number theory, and more.
