Induced subgraphs and tree-decompositions VII. Basic obstructions in -free graphs

Tara Abrishami, Bogdan Alecu, Maria Chudnovsky +2

We say a class of graphs is clean if for every positive integer there exists a positive integer such that every graph in with treewidth more…

Induced subgraphs and tree decompositions VI. Graphs with 2-cutsets

Tara Abrishami, Maria Chudnovsky, Sepehr Hajebi +1

This paper continues a series of papers investigating the following question: which hereditary graph classes have bounded treewidth? We call a graph -clean if it does not contai…

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…

Induced subgraphs and tree decompositions V. Small components of big vertices

Bogdan Alecu, Maria Chudnovsky, Kristina Vušković

Aboulker, Adler, Kim, Sintiari, and Trotignon conjectured that every graph with bounded maximum degree and large treewidth must contain, as an induced subgraph, a large subdivided…

Bipartite graphs with no minor

Maria Chudnovsky, Alex Scott, Paul Seymour +1

A theorem of Mader shows that every graph with average degree at least eight has a minor, and this is false if we replace eight by any smaller constant. Replacing average deg…

Induced subgraphs and tree decompositions IV. (Even hole, diamond, pyramid)-free graphs

Tara Abrishami, Maria Chudnovsky, Sepehr Hajebi +1

A hole in a graph is an induced cycle of length at least four, and an even hole is a hole of even length. The diamond is the graph obtained from the complete graph by rem…
