Random graphs: models and asymptotic characteristics

ME Zhukovskii, AM Raigorodskii - Russian Mathematical Surveys, 2015 - iopscience.iop.org
This is a survey of known results related to the asymptotic behaviour of the probabilities of
first-order properties of random graphs. The results presented in this paper are concerned …

[HTML][HTML] Estimating the r-colorability threshold for a random hypergraph

DA Shabanov - Discrete Applied Mathematics, 2020 - Elsevier
The paper deals with estimating the r-colorability threshold for a random k-uniform
hypergraph in the binomial model H (n, k, p). We consider the sparse case, when the …

Sharp bounds for the chromatic number of random Kneser graphs

S Kiselev, A Kupavskii - arXiv preprint arXiv:1810.01161, 2018 - arxiv.org
Given positive integers $ n\ge 2k $, the {\it Kneser graph} $ KG_ {n, k} $ is a graph whose
vertex set is the collection of all $ k $-element subsets of the set $\{1,\ldots, n\} $, with edges …

Random Kneser graphs and hypergraphs

A Kupavskii - arXiv preprint arXiv:1612.03868, 2016 - arxiv.org
The Kneser graph $ KG_ {n, k} $ is the graph whose vertices are the $ k $-element subsets
of $[n], $ with two vertices adjacent if and only if the corresponding sets are disjoint. A …

A generalization of Kneser graphs

AV Bobu, AE Kupriyanov, AM Raigorodskii - Mathematical Notes, 2020 - Springer
Graphs which are analogs of Kneser graphs are studied. The problem of determining the
chromatic numbers of these graphs is considered. It is shown that their structure is similar to …

[HTML][HTML] On the chromatic number of random subgraphs of a certain distance graph

MM Pyaderkin - Discrete Applied Mathematics, 2019 - Elsevier
We study the chromatic number of the graph G (n, 3, 1), whose vertices are all 3-element
subsets of [n]={1, 2,…, n}, and there is an edge between two vertices if the corresponding …

On a bound in extremal combinatorics

AM Raigorodskii, AA Sagdeev - Doklady Mathematics, 2018 - Springer
A new statement of a recent theorem of [1, 2] on the maximum number of edges in a
hypergraph with forbidden cardinalities of edge intersections is given. This statement is …
