Permutation graphs and the Abelian sandpile model, tiered trees and non-ambiguous binary trees
Mark Dukes, Thomas Selig, Jason P. Smith +1
A permutation graph is a graph whose edges are given by inversions of a permutation. We study the Abelian sandpile model (ASM) on such graphs. We exhibit a bijection between recurr…

The Abelian sandpile model on Ferrers graphs -- A classification of recurrent configurations
Mark Dukes, Thomas Selig, Jason P. Smith +1
We classify all recurrent configurations of the Abelian sandpile model (ASM) on Ferrers graphs. The classification is in terms of decorations of EW-tableaux, which undecorated are…
