A Note on Packing of Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We say that two n-vertex hypergraphs H1 and H2 pack if they can be found as edge-disjoint subhypergraphs of the complete hypergraph Kn. Whilst the problem of packing of graphs (i.e., 2-uniform hypergraphs) has been studied extensively since seventies ...

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 ...

Tensor Entropy for Uniform Hypergraphs [PDF]

open access: yesIEEE Transactions on Network Science and Engineering, 2020
In this paper, we develop the notion of entropy for uniform hypergraphs via tensor theory. We employ the probability distribution of the generalized singular values, calculated from the higher-order singular value decomposition of the Laplacian tensors, to fit into the Shannon entropy formula.

On the α-Spectral Radius of Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
For 0 ≤ α ---lt--- 1 and a uniform hypergraph G, the α-spectral radius of G is the largest H-eigenvalue of αD(G)+(1−α)A(G), where D(G) and A(G) are the diagonal tensor of degrees and the adjacency tensor of G, respectively. We give upper bounds for the α-

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

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 ...

Bounding the Number of Minimal Transversals in Tripartite 3-Uniform Hypergraphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
We focus on the maximum number of minimal transversals in 3-partite 3-uniform hypergraphs on n vertices. Those hypergraphs (and their minimal transversals) are commonly found in database applications.

On the distance energy of k-uniform hypergraphs

open access: yesSpecial Matrices, 2023
In this article, we extend the concept of distance energy for hypergraphs. We first establish a relation between the distance energy and the distance spectral radius.
