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…

Computing Homotopy Types of Directed Flag Complexes

Dejan Govc

Combinatorially and stochastically defined simplicial complexes often have the homotopy type of a wedge of spheres. A prominent conjecture of Kahle quantifies this precisely for th…

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…

How many simplices are needed to triangulate a Grassmannian?

Dejan Govc, Wacław Marzantowicz, Petar Pavešić

We compute a lower bound for the number of simplices that are needed to triangulate the Grassmann manifold . In particular, we show that the number of top-dimens…

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…
