Given a collection $\mathcal {G}=(G_1,\dots, G_h) $ of graphs on the same vertex set $ V $
of size $ n $, an $ h $-edge graph $ H $ on the vertex set $ V $ is a $\mathcal {G} …

Decompositions into spanning rainbow structures

R Montgomery, A Pokrovskiy… - Proceedings of the …, 2019 - Wiley Online Library
A subgraph of an edge‐coloured graph is called rainbow if all its edges have distinct
colours. The study of rainbow subgraphs goes back more than 200 years to the work of …

[HTML][HTML] Decompositions into isomorphic rainbow spanning trees

S Glock, D Kühn, R Montgomery, D Osthus - Journal of Combinatorial …, 2021 - Elsevier
A subgraph of an edge-coloured graph is called rainbow if all its edges have distinct colours.
Our main result implies that, given any optimal colouring of a sufficiently large complete …

An algorithmic proof of the Lovász local lemma via resampling oracles

NJA Harvey, J Vondrák - 2015 IEEE 56th Annual Symposium …, 2015 - ieeexplore.ieee.org
The Lovasz Local Lemma is a seminal result in probabilistic combinatorics. It gives a
sufficient condition on a probability space and a collection of events for the existence of an …

Halfway to Rota's basis conjecture

M Bucić, M Kwan, A Pokrovskiy… - International …, 2020 - academic.oup.com
In 1989, Rota made the following conjecture. Given bases in an-dimensional vector space,
one can always find disjoint bases of, each containing exactly one element from each (we …

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 …

[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 …

A rainbow blow‐up lemma

S Glock, F Joos - Random Structures & Algorithms, 2020 - Wiley Online Library
We prove a rainbow version of the blow‐up lemma of Komlós, Sárközy, and Szemerédi for
μn‐bounded edge colorings. This enables the systematic study of rainbow embeddings of …

Long rainbow cycles and Hamiltonian cycles using many colors in properly edge-colored complete graphs

J Balogh, T Molla - European Journal of Combinatorics, 2019 - Elsevier
We prove two results regarding cycles in properly edge-colored graphs. First, we make a
small improvement to the recent breakthrough work of Alon, Pokrovskiy and Sudakov who …

NJA Harvey, J Vondrák - SIAM Journal on Computing, 2020 - SIAM
The Lovász local lemma is a seminal result in probabilistic combinatorics. It gives a sufficient
condition on a probability space and a collection of events for the existence of an outcome …
