Rainbow Hamilton cycle in hypergraph system

Y Tang, B Wang, G Wang, G Yan - arXiv preprint arXiv:2302.00080, 2023 - arxiv.org
In this paper, we develop a new rainbow Hamilton framework, which is of independent
interest, settling the problem proposed by Gupta, Hamann, M\"{u} yesser, Parczyk, and …

Rainbow spanning structures in graph and hypergraph systems

Y Cheng, J Han, B Wang, G Wang - arXiv preprint arXiv:2105.10219, 2021 - arxiv.org
We study the following rainbow version of subgraph containment problems in a family of
(hyper) graphs, which generalizes the classical subgraph containment problems in a single …

A rainbow Dirac's theorem

M Coulson, G Perarnau - SIAM Journal on Discrete Mathematics, 2020 - SIAM
A famous theorem of Dirac states that any graph on n vertices with minimum degree at least
n/2 has a Hamilton cycle. Such graphs are called Dirac graphs. Strengthening this result, 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 …

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 …

The n-queens completion problem

S Glock, D Munhá Correia, B Sudakov - Research in the Mathematical …, 2022 - Springer
An n-queens configuration is a placement of n mutually non-attacking queens on an n× n
chessboard. The n-queens completion problem, introduced by Nauck in 1850, is to decide …

Counting Hamilton cycles in Dirac hypergraphs

S Glock, S Gould, F Joos, D Kühn… - … Probability and Computing, 2021 - cambridge.org
A tight Hamilton cycle in a k-uniform hypergraph (k-graph) G is a cyclic ordering of the
vertices of G such that every set of k consecutive vertices in the ordering forms an edge …

Towards a hypergraph version of the P\'osa-Seymour conjecture

M Pavez-Signé, N Sanhueza-Matamala… - arXiv preprint arXiv …, 2021 - arxiv.org
We prove that for fixed $ r\ge k\ge 2$, every $ k $-uniform hypergraph on $ n $ vertices
having minimum codegree at least $(1-(\binom {r-1}{k-1}+\binom {r-2}{k-2})^{-1}) n+ o (n) …

Rainbow spanning structures in graph and hypergraph systems

Y Cheng, J Han, B Wang, G Wang - Forum of Mathematics, Sigma, 2023 - cambridge.org
We study the following rainbow version of subgraph containment problems in a family of
(hyper) graphs, which generalizes the classical subgraph containment problems in a single …

Rainbow subgraphs and their applications

A Pokrovskiy - Surveys in Combinatorics, 2022 - cambridge.org
A subgraph of an edge-coloured graph is called rainbow if all its edges have distinct colours.
The study of rainbow subgraphs goes back to the work of Euler on Latin squares. This article …
