A class of inequalities relating degrees of adjacent nodes to the average degree in edge-weighted uniform hypergraphs [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2005
In 1986, Johnson and Perry proved a class of inequalities for uniform hypergraphs which included the following: for any such hypergraph, the geometric mean over the hyperedges of the geometric means of the degrees of the nodes on the hyperedge is no less

Tight Euler tours in uniform hypergraphs - computational aspects [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
By a tight tour in a $k$-uniform hypergraph $H$ we mean any sequence of its vertices $(w_0,w_1,\ldots,w_{s-1})$ such that for all $i=0,\ldots,s-1$ the set $e_i=\{w_i,w_{i+1}\ldots,w_{i+k-1}\}$ is an edge of $H$ (where operations on indices are computed ...

Edge Balanced 3-Uniform Hypergraph Designs

open access: yesMathematics, 2020
In this paper, we completely determine the spectrum of edge balanced H-designs, where H is a 3-uniform hypergraph with 2 or 3 edges, such that H has strong chromatic number χs(H)=3.

Decomposing complete 3-uniform hypergraph K_{n}^{(3)} into 7-cycles [PDF]

open access: yesOpuscula Mathematica, 2019
We use the Katona-Kierstead definition of a Hamiltonian cycle in a uniform hypergraph. A decomposition of complete \(k\)-uniform hypergraph \(K^{(k)}_{n}\) into Hamiltonian cycles was studied by Bailey-Stevens and Meszka-Rosa. For \(n\equiv 2,4,5\pmod 6\)

The Largest Laplacian and Signless Laplacian H-Eigenvalues of a Uniform Hypergraph [PDF]

open access: yes, 2013
In this paper, we show that the largest Laplacian H-eigenvalue of a $k$-uniform nontrivial hypergraph is strictly larger than the maximum degree when $k$ is even. A tight lower bound for this eigenvalue is given.

Hypergraph partitioning using tensor eigenvalue decomposition. [PDF]

open access: yesPLoS ONE, 2023
Hypergraphs have gained increasing attention in the machine learning community lately due to their superiority over graphs in capturing super-dyadic interactions among entities.

The Evolution of Cooperation in Multigames with Uniform Random Hypergraphs

open access: yesMathematics, 2023
How to explain the emergence of cooperative behavior remains a significant problem. As players may hold diverse perceptions on a particular dilemma, the concept of multigames has been introduced.

Constructing and sampling partite, 3-uniform hypergraphs with given degree sequence. [PDF]

open access: yesPLoS ONE
Partite, 3-uniform hypergraphs are 3-uniform hypergraphs in which each hyperedge contains exactly one point from each of the 3 disjoint vertex classes. We consider the degree sequence problem of partite, 3-uniform hypergraphs, that is, to decide if such ...

The Wiener index, degree distance index and Gutman index of composite hypergraphs and sunflower hypergraphs [PDF]

open access: yesHeliyon, 2022
Topological invariants are numerical parameters of graphs or hypergraphs that indicate its topology and are known as graph or hypergraph invariants. In this paper, topological indices of hypergraphs such as Wiener index, degree distance index and Gutman ...
