Embedding spanning bounded degree graphs in randomly perturbed graphs

J Böttcher, R Montgomery, O Parczyk, Y Person - Mathematika, 2020 - Wiley Online Library
We study the model G α∪ G (n, p) of randomly perturbed dense graphs, where G α is any n‐
vertex graph with minimum degree at least α n and G (n, p) is the binomial random graph …

Random perturbation of sparse graphs

M Hahn-Klimroth, GS Maesaka, Y Mogge… - arxiv preprint arxiv …, 2020 - arxiv.org
In the model of randomly perturbed graphs we consider the union of a deterministic graph
$\mathcal {G} _\alpha $ with minimum degree $\alpha n $ and the binomial random graph …

Optimal threshold for a random graph to be 2-universal

A Ferber, G Kronenberg, K Luh - Transactions of the American …, 2019 - ams.org
For a family of graphs $\mathcal {F} $, a graph $ G $ is $\mathcal {F} $-universal if $ G $
contains every graph in $\mathcal {F} $ as a (not necessarily induced) subgraph. For the …

The bandwidth theorem in sparse graphs

P Allen, J Böttcher, J Ehrenmüller, A Taraz - arxiv preprint arxiv …, 2016 - arxiv.org
The bandwidth theorem [Mathematische Annalen, 343 (1): 175--205, 2009] states that any $
n $-vertex graph $ G $ with minimum degree $\big (\tfrac {k-1}{k}+ o (1)\big) n $ contains all …

Large-scale structures in random graphs.

J Böttcher - BCC, 2017 - books.google.com
In recent years there has been much progress in graph theory on questions of the following
type. What is the threshold for a certain large substructure to appear in a random graph …

Spanning universality in random graphs

A Ferber, R Nenadov - Random Structures & Algorithms, 2018 - Wiley Online Library
A graph is said to be‐universal if it contains every graph with n vertices and maximum
degree at most Δ as a subgraph. Dellamonica, Kohayakawa, Rödl and Ruciński used a …

[HTML][HTML] 2-universality in randomly perturbed graphs

O Parczyk - European Journal of Combinatorics, 2020 - Elsevier
A graph G is called universal for a family of graphs F if it contains every element F∈ F as a
subgraph. Let F (n, 2) be the family of all graphs with maximum degree 2. Ferber et al.(2019) …

The threshold bias of the clique-factor game

A Liebenau, R Nenadov - Journal of Combinatorial Theory, Series B, 2022 - Elsevier
Let r≥ 4 be an integer and consider the following game on the complete graph K n for n∈ r
Z: Two players, Maker and Breaker, alternately claim previously unclaimed edges of K n …
