Unavoidable butterfly minors in digraphs of large cycle rank

Meike Hatzel, O-joung Kwon, Myounghwan Lee +1

Cycle rank is one of the depth parameters for digraphs introduced by Eggan in 1963. We show that there exists a function such that every digraph of cyc…

The Erdős-Pósa property for circle graphs as vertex-minors

Rutger Campbell, J. Pascal Gollin, Meike Hatzel +4

We prove that for any circle graph with at least one edge and for any positive integer , there exists an integer so that every graph either has a vertex-minor…

Odd coloring graphs with linear neighborhood complexity

James Davies, Meike Hatzel, Kolja Knauer +2

We prove that any class of graphs with linear neighborhood complexity has bounded improper odd chromatic number. As a result, if is the class of all circle graphs, or…

Girth in -representable matroids

James Davies, Meike Hatzel, Kolja Knauer +2

We prove a conjecture of Geelen, Gerards, and Whittle that for any finite field and any integer , every cosimple -representable matroid with sufficiently large gi…

On graphs with a simple structure of maximal cliques

J. Pascal Gollin, Meike Hatzel, Sebastian Wiederrecht

We say that a hereditary graph class is \emph{clique-sparse} if there is a constant such that for every graph , every vertex of $G…

Strongly sublinear separators and bounded asymptotic dimension for sphere intersection graphs

James Davies, Agelos Georgakopoulos, Meike Hatzel +1

In this paper, we consider the class of sphere intersection graphs in for . We show that for each integer , the class of all graphs in $…
