A survey of -boundedness

Alex Scott, Paul Seymour

If a graph has bounded clique number, and sufficiently large chromatic number, what can we say about its induced subgraphs? András Gyárfás made a number of challenging conjectures…

Sparse graphs with no polynomial-sized anticomplete pairs

Maria Chudnovsky, Jacob Fox, Alex Scott +2

A graph is "-free" if it has no induced subgraph isomorphic to . A conjecture of Conlon, Fox and Sudakov states that for every graph , there exists such that in ever…

Proof of the Kalai-Meshulam conjecture

Maria Chudnovsky, Alex Scott, Paul Seymour +1

Let be a graph, and let be the sum of , over all stable sets . If is a cycle with length divisible by three, then . Motivated by topologica…

Pure pairs. I. Trees and linear anticomplete pairs

Maria Chudnovsky, Alex Scott, Paul Seymour +1

The Erdos-Hajnal Conjecture asserts that for every graph H there is a constant c > 0 such that every graph G that does not contain H as an induced subgraph has a clique or stable s…

Induced subgraphs of graphs with large chromatic number. XIII. New brooms

Alex Scott, Paul Seymour

Gyárfás and Sumner independently conjectured that for every tree , the class of graphs not containing as an induced subgraph is -bounded, that is, the chromatic numbers o…

Size reconstructibility of graphs

Carla Groenland, Hannah Guggiari, Alex Scott

The deck of a graph is given by the multiset of (unlabelled) subgraphs . The subgraphs are referred to as the cards of . Brown and Fenner recently s…
