Excluding paths and bicliques

Maria Chudnovsky, Julien Codsi, Matjaž Krnc +1

The paper improves the known Ramsey‑type bound on the maximum length of a path in graphs that exclude a fixed path and a biclique as induced subgraphs, showing it can be taken sing…

Induced-Minor-Closed Classes have Linear, Square-Root, or Sub-Polynomial Tree-Independence

Maria Chudnovsky, Julien Codsi, Ajaykrishnan E S +1

The paper shows that any graph either contains a large complete bipartite graph or a large wall as an induced minor, or else its tree‑independence number grows sub‑polynomially, le…

Coarse Balanced Separators in Biclique-Induced-Minor-Free Graphs

Maria Chudnovsky, Julien Codsi, Claire Kaneshiro

It is a classical theorem of Robertson and Seymour (1986) that the treewidth of a graph is linearly related to its separation number: the smallest integer such that, for every…

Induced Minors and Coarse Tree Decompositions

Maria Chudnovsky, Julien Codsi, Ajaykrishnan E S +1

Let be a graph, be a vertex set in and be a positive integer. The distance -independence number of is the size of the largest subset $I \subse…

Tree-independence number and forbidden induced subgraphs: excluding a -vertex path and a -biclique

Maria Chudnovsky, Julien Codsi, J. Pascal Gollin +2

We show that for every positive integer there exists an integer such that every graph that contains no induced subgraph isomorphic to either the -vertex path or…

Induced minors and subpolynomial treewidth

Maria Chudnovsky, Julien Codsi, David Fischer +1

Given a family of graphs, we say that a graph is -induced-minor-free if no induced minor of is isomorphic to a member of , We denote…
