Tree decompositions whose trees are subgraphs: An application of Simon's factorization
Romain Bourneuf, Gwenaël Joret, Piotr Micek +2
We show that every connected graph has a tree decomposition indexed by a tree such that is a subgraph of and the width of the tree decomposition is bounded from abo…
On cuts of small chromatic number in sparse graphs
Guillaume Aubian, Marthe Bonamy, Romain Bourneuf +2
For a given integer , let denote the supremum such that every sufficiently large graph with average degree less than admits a separator $X \subseteq…
On polynomial degree-boundedness
Romain Bourneuf, Matija Bucić, Linda Cook +1
We prove a conjecture of Bonamy, Bousquet, Pilipczuk, Rzążewski, Thomassé, and Walczak, that for every graph , there is a polynomial such that for every positive integer …
Factoring Pattern-Free Permutations into Separable ones
Édouard Bonnet, Romain Bourneuf, Colin Geniet +1
We show that for any permutation there exists an integer such that every permutation avoiding as a pattern is a product of at most separable permutations. In ot…
A tamed family of triangle-free graphs with unbounded chromatic number
Édouard Bonnet, Romain Bourneuf, Julien Duron +3
We construct a hereditary class of triangle-free graphs with unbounded chromatic number, in which every non-trivial graph either contains a pair of non-adjacent twins or has an edg…
