Graph labeling
JA Gallian - The electronic journal of combinatorics, 2012 - combinatorics.org
A graph labeling is an assignment of integers to the vertices or edges, or both, subject to
certain conditions. Graph labelings were first introduced in the mid 1960s. In the intervening …

A proof of Ringel's conjecture
R Montgomery, A Pokrovskiy, B Sudakov - Geometric and Functional …, 2021 - Springer
A typical decomposition question asks whether the edges of some graph G can be
partitioned into disjoint copies of another graph H. One of the oldest and best known …

Essentially tight bounds for rainbow cycles in proper edge-colourings
An edge-coloured graph is said to be rainbow if no colour appears more than once.
Extremal problems involving rainbow objects have been a focus of much research over the …

Resolution of the Oberwolfach problem
The Oberwolfach problem, posed by Ringel in 1967, asks for a decomposition of K2n+ 1 into
edge-disjoint copies of a given 2-factor. We show that this can be achieved for all large n …

Pseudorandom hypergraph matchings
A celebrated theorem of Pippenger states that any almost regular hypergraph with small
codegrees has an almost perfect matching. We show that one can find such an almost …

Spanning trees in dense directed graphs
A Kathapurkar, R Montgomery - Journal of Combinatorial Theory, Series B, 2022 - Elsevier
In 2001, Komlós, Sárközy and Szemerédi proved that, for each α> 0, there is some c> 0 and
n 0 such that, if n≥ n 0, then every n-vertex graph with minimum degree at least (1/2+ α) n …

A rainbow blow-up lemma for almost optimally bounded edge-colourings
A subgraph of an edge-coloured graph is called rainbow if all its edges have different
colours. We prove a rainbow version of the blow-up lemma of Komlós, Sárközy, and …
