Far-apart Erdős--Pósa property of long cycles

Maria Chudnovsky, Vida Dujmović, Gwenaël Joret +4

The authors prove that for any graph, either it contains many cycles of length at least ℓ that are pairwise far apart, or a small vertex set can be removed to eliminate all such lo…

Induced subgraph density. IV. New graphs with the Erdős-Hajnal property

Tung Nguyen, Alex Scott, Paul Seymour

Erdős and Hajnal conjectured that for every graph , there exists such that every -free graph has a clique or a stable set of size at least (a graph is -…

Short reachability networks

Carla Groenland, Tom Johnston, Jamie Radcliffe +1

We investigate the following generalisation of permutation networks. We say a sequence of transpositions in forms a -reachability network if, for ev…

Shotgun assembly of random graphs

Tom Johnston, Gal Kronenberg, Alexander Roberts +1

In the graph shotgun assembly problem, we are given the balls of radius around each vertex of a graph and asked to reconstruct the graph. We study the shotgun assembly of the E…

Improved bounds for 1-independent percolation on

Paul Balister, Tom Johnston, Michael Savery +1

A 1-independent bond percolation model on a graph is a probability distribution on the spanning subgraphs of in which, for all vertex-disjoint sets of edges and

A multidimensional Ramsey Theorem

António Girão, Gal Kronenberg, Alex Scott

Ramsey theory is a central and active branch of combinatorics. Although Ramsey numbers for graphs have been extensively investigated since Ramsey's work in the 1930s, there is stil…
