Chip firing
WebJan 20, 1992 · The chip firing game introduced in [7] starts by assigning to each vertex a finite number of chips. A legal move consists of selecting a vertex which has at least as many chips as its degree, and passing one chip to each of its neighbouring vertices. This is called firing a vertex. The procedure continues as long as there exists legal moves to ... WebJun 27, 2024 · These chip-firing relations can be interpreted as a “tropical” notion of linear equivalence for an entirely combinatorial divisor theory on G. In this framework we may then study degenerations that have low geometric complexity, for instance, degenerations to rational curves, but high combinatorial complexity in G .

In 1989, Bitar conjectured that the period of a parallel chip-firing game with n vertices is at most n. Though this conjecture was disproven in 1994 by Kiwi et. al., it has been proven for particular classes of graphs, specifically trees (Bitar …
WebMay 1, 2024 · Chip-firing on an undirected graph is defined as chip-firing on the corresponding bidirected graph. The following theorem was proved by Björner and Lovász. They state their theorem only for chip-distributions x ∈ Chip (G) with x ≥ 0 G, but it is easy to check that the proof also works for chip-distributions with negative entries.

WebApr 18, 2024 · 1.2 Divisors on a Graph and the Chip-Firing Game. We started by giving an algebraic description of the critical group as the torsion part of the cokernel of the Laplacian matrix of G, but one can also approach it from a more combinatorial point of view via the chip-firing game, which was originally introduced by Biggs in . In order to define ... WebA variant of the chip-firing game on a graph is defined. It is shown that the set of configurations that are stable and recurrent for this game can be given the structure of an abelian group, and that the order of the group is equal to the tree number of the graph. In certain cases the game can be used to illuminate the structure of the group.

WebAug 16, 2024 · Jim Propp recently introduced a variant of chip-firing on a line where the chips are given distinct integer labels. Hopkins, McConville, and Propp showed that this process is confluent from some (but not all) initial configurations of chips.
