An application of neighbourhoods in digraphs to the classification of binary dynamics

Pedro Conceição, Dejan Govc, Jānis Lazovskis +3

A binary state on a graph means an assignment of binary values to its vertices. For example, if one encodes a network of spiking neurons as a directed graph, then the spikes produc…

Asymptotic Behaviour of the Containment of Certain Mesh Patterns

Dejan Govc, Jason P. Smith

We present some results on the proportion of permutations of length containing certain mesh patterns as grows large, and give exact enumeration results in some cases. In pa…

Complexes of Tournaments, Directionality Filtrations and Persistent Homology

Dejan Govc, Ran Levi, Jason P. Smith

Complete digraphs are referred to in the combinatorics literature as tournaments. We consider a family of semi-simplicial complexes, that we refer to as "tournaplexes", whose simpl…

Computing persistent homology of directed flag complexes

Daniel Luetgehetmann, Dejan Govc, Jason Smith +1

We present a new computing package Flagser, designed to construct the directed flag complex of a finite directed graph, and compute persistent homology for flexibly defined filtrat…

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…
