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

N Alon, M Bucić, L Sauermann, D Zakharov… - arXiv preprint arXiv …, 2023 - arxiv.org
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

S Glock, F Joos, J Kim, D Kühn… - Journal of the European …, 2021 - content.ems.press
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

S Ehard, S Glock, F Joos - Combinatorics, Probability and Computing, 2020 - cambridge.org
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 …

Rainbow structures in locally bounded colorings of graphs

J Kim, D Kühn, A Kupavskii… - Random Structures & …, 2020 - Wiley Online Library
We study approximate decompositions of edge‐colored quasirandom graphs into rainbow
spanning structures: an edge‐coloring of a graph is locally‐bounded if every vertex is …

A rainbow blow-up lemma for almost optimally bounded edge-colourings

S Ehard, S Glock, F Joos - Forum of Mathematics, Sigma, 2020 - cambridge.org
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 …

[HTML][HTML] Linearly many rainbow trees in properly edge-coloured complete graphs

A Pokrovskiy, B Sudakov - Journal of Combinatorial Theory, Series B, 2018 - Elsevier
A subgraph of an edge-coloured complete graph is called rainbow if all its edges have
different colours. The study of rainbow decompositions has a long history, going back to the …
