Sharp bounds for the fractional chromatic number of high-girth -degenerate graphs

Peter Allen, Abhishek Dhawan, Jonathan A. Noel

The paper proves tight upper and lower bounds of order d/log d for the fractional chromatic number of high‑girth d‑degenerate graphs, provides a randomized algorithm achieving the…

Breaking the Bollobás-Eldridge-Catlin Barrier for Bipartite Graphs

Peter Allen, Julia Böttcher, Julia Böttcher +2

The celebrated Bollobás-Eldridge-Catlin packing conjecture states that every -vertex graph with minimum degree at least contains every -vert…

On Ramsey-type problems for paths and cycles with few colour changes

Peter Allen, Julia Böttcher, Dennis Clemens +3

In 1967, Gerencser and Gyárfás determined the exact values of the two-colour Ramsey numbers of paths. In a footnote, they made the following observation: Every -edge-coloured…

A robust Corrádi--Hajnal Theorem

Peter Allen, Julia Böttcher, Jan Corsten +5

For a graph and , we denote by the random sparsification of obtained by keeping each edge of independently, with probability . We show that there ex…

Ramsey numbers for 1-degenerate 3-graphs

Peter Allen, Simona Boyadzhiyska, Matías Pavez-Signé

We construct a 3-uniform 1-degenerate hypergraph on vertices whose 2-colour Ramsey number is . This shows that all remaining open cases of the hyper…

Bounds for Hypergraph Universality

Peter Allen, Julia Böttcher, Jasmin Katz

A graph is said to be universal for a class of graphs if contains a copy of every as a subgraph. The number of edges required for a host…
