Induced subgraphs and tree decompositions V. One neighbor in a hole

Tara Abrishami, Bogdan Alecu, Maria Chudnovsky +3

What are the unavoidable induced subgraphs of graphs with large treewidth? It is well-known that the answer must include a complete graph, a complete bipartite graph, all subdivisi…

Polynomial bounds for chromatic number VII. Disjoint holes

Maria Chudnovsky, Alex Scott, Paul Seymour +1

A hole in a graph is an induced cycle of length at least four, and a -multihole in is a set of pairwise disjoint and nonadjacent holes. It is well known that if does…

Strengthening Rodl's theorem

Maria Chudnovsky, Alex Scott, Paul Seymour +1

What can be said about the structure of graphs that do not contain an induced copy of some graph H? Rodl showed in the 1980s that every H-free graph has large parts that are very d…

Concatenating bipartite graphs

Maria Chudnovsky, Patrick Hompe, Alex Scott +2

Let and let be disjoint nonempty subsets of a graph , where every vertex in has at least neighbours in , and every vertex in has at least…

-colouring -free graphs in subexponential time

Carla Groenland, Karolina Okrasa, Pawel Rzążewski +3

A graph is called -free if it does not contain the path on vertices as an induced subgraph. Let be a multigraph with the property that any two distinct vertices share…

Four-coloring -free graphs. II. Finding an excellent precoloring

Maria Chudnovsky, Sophie Spirkl, Mingxian Zhong

This is the second paper in a series of two. The goal of the series is to give a polynomial time algorithm for the -coloring problem and the -precoloring extension problem re…

Four-coloring -free graphs. I. Extending an excellent precoloring

Maria Chudnovsky, Sophie Spirkl, Mingxian Zhong

This is the first paper in a series whose goal is to give a polynomial time algorithm for the -coloring problem and the -precoloring extension problem restricted to the class…
