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

Signless normalized Laplacian for hypergraphs [PDF]
Electronic Journal of Graph Theory and Applications, 2022 The spectral theory of the normalized Laplacian for chemical hypergraphs is further investigated. The signless normalized Laplacian is introduced and it is shown that its spectrum for classical hypergraphs coincides with the spectrum of the normalized ...

Complex Neutrosophic Hypergraphs: New Social Network Models
Algorithms, 2019 A complex neutrosophic set is a useful model to handle indeterminate situations with a periodic nature. This is characterized by truth, indeterminacy, and falsity degrees which are the combination of real-valued amplitude terms and complex-valued phase ...

Hypergraph and Uncertain Hypergraph Representation Learning Theory and Methods
Mathematics, 2022 With the advent of big data and the information age, the data magnitude of various complex networks is growing rapidly. Many real-life situations cannot be portrayed by ordinary networks, while hypergraphs have the ability to describe and characterize ...

Sharp Bounds on the Spectral Radii of Uniform Hypergraphs concerning Diameter or Clique Number
Discrete Dynamics in Nature and Society, 2021 In this paper, we defined two classes of hypergraphs, hyperbugs and kite hypergraphs. We show that balanced hyperbugs maximize the spectral radii of hypergraphs with fixed number of vertices and diameter and kite hypergraphs minimize the spectral radii ...

On Clustering Detection Based on a Quadratic Program in Hypergraphs
Journal of Mathematics, 2022 A proper cluster is usually defined as maximally coherent groups from a set of objects using pairwise or more complicated similarities. In general hypergraphs, clustering problem refers to extraction of subhypergraphs with a higher internal density, for ...

Generalized Hypergraph Coloring
Discussiones Mathematicae Graph Theory, 2021 A smooth hypergraph property 𝒫 is a class of hypergraphs that is hereditary and non-trivial, i.e., closed under induced subhypergraphs and it contains a non-empty hypergraph but not all hypergraphs.
