Eternal Independent Sets in Graphs

open access: yesTheory and Applications of Graphs, 2016
The use of mobile guards to protect a graph has received much attention in the literature of late in the form of eternal dominating sets, eternal vertex covers and other models of graph protection.

On the Independence Number of Cayley Digraphs of Clifford Semigroups

open access: yesMathematics, 2023
Let S be a Clifford semigroup and A a subset of S. We write Cay(S,A) for the Cayley digraph of a Clifford semigroup S relative to A. The (weak, path, weak path) independence number of a graph is the maximum cardinality of an (weakly, path, weakly path ...

Hypergraph Independent Sets

open access: yesCombinatorics, Probability and Computing, 2012
The study of extremal problems related to independent sets in hypergraphs is a problem that has generated much interest. There are a variety of types of independent sets in hypergraphs depending on the number of vertices from an independent set allowed in an edge.

Counting Independent Sets in Hypergraphs [PDF]

open access: yesCombinatorics, Probability and Computing, 2014
Let G be a triangle-free graph with n vertices and average degree t. We show that G contains at least ${\exp\biggl({1-n^{-1/12})\frac{1}{2}\frac{n}{t}\ln t} \biggl(\frac{1}{2}\ln t-1\biggr)\biggr)}$ independent sets. This improves a recent result of the first and third authors [8]. In particular, it implies that as n → ∞, every triangle-free graph on n

Large Independent Sets on Random d-Regular Graphs with Fixed Degree d

open access: yesComputation, 2023
The maximum independent set problem is a classic and fundamental combinatorial challenge, where the objective is to find the largest subset of vertices in a graph such that no two vertices are adjacent.

Clique versus independent set

open access: yesEuropean Journal of Combinatorics, 2014
Yannakakis' Clique versus Independent Set problem (CL-IS) in communication complexity asks for the minimum number of cuts separating cliques from stable sets in a graph, called CS-separator. Yannakakis provides a quasi-polynomial CS-separator, i.e. of size $O(n^{\log n})$, and addresses the problem of finding a polynomial CS-separator. This question is

Ultrafilters and Independent Sets [PDF]

open access: yesTransactions of the American Mathematical Society, 1972
Independent families of sets and of functions are used to prove some theorems about ultrafilters. All of our results are well known to be provable from some form of the generalized continuum hypothesis, but had remained open without such an assumption.

Independent Sets in Polarity Graphs [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2016
Given a projective plane $ $ and a polarity $ $ of $ $, the corresponding polarity graph is the graph whose vertices are the points of $ $, and two distinct points $p_1$ and $p_2$ are adjacent if $p_1$ is incident to $p_2^{ }$ in $ $. A well-known example of a polarity graph is the Erd s-R nyi orthogonal polarity graph $ER_q$, which appears ...
