Far-apart Erdős--Pósa property of long cycles

Maria Chudnovsky, Vida Dujmović, Gwenaël Joret +4

The authors prove that for any graph, either it contains many cycles of length at least ℓ that are pairwise far apart, or a small vertex set can be removed to eliminate all such lo…

Adjacency labelling for proper minor-closed graph classes

Vida Dujmović, Cyril Gavoille, Gwenaël Joret +3

The paper proves that every proper minor‑closed class of graphs admits an adjacency labeling scheme using (1+o(1))·log₂ n bits, equivalently showing the existence of an n^{1+o(1)}‑…

3-Colouring Graphs Excluding a Fixed Minor

Vida Dujmović, Hussein Houdrouge, Pat Morin

We show that, for every fixed graph , every -vertex graph that excludes as a minor is -colourable with clustering . That is, there exists a function…

Erdős--Pósa property of cycles that are far apart

Vida Dujmović, Gwenaël Joret, Piotr Micek +1

We prove that there exist functions such that for all nonnegative integers and , for every graph , either contains cycles such that…

2-dimensional unit vector flows

Hussein Houdrouge, Bobby Miraftab, Pat Morin

We study -dimensional unit vector flows on graphs, that is, nowhere-zero flows that assign to each oriented edge a unit vector in . We give a new geometric charac…

Local certification of geometric graph classes

Oscar Defrain, Louis Esperet, Aurélie Lagoutte +2

The goal of local certification is to locally convince the vertices of a graph that satisfies a given property. A prover assigns short certificates to the vertices of the g…
