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 ...

Hyperbolic Hypergraphs for Sequential Recommendation [PDF]
International Conference on Information and Knowledge Management, 2021 Hypergraphs have been becoming a popular choice to model complex, non-pairwise, and higher-order interactions for recommender systems. However, compared with traditional graph-based methods, the constructed hypergraphs are usually much sparser, which ...

Generalized Hypergraph Coloring
Discussiones Mathematicae Graph Theory, 2021 A smooth hypergraph property đť’« 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.

Synchronization of phase oscillators on complex hypergraphs. [PDF]
Chaos, 2022 We study the effect of structured higher-order interactions on the collective behavior of coupled phase oscillators. By combining a hypergraph generative model with dimensionality reduction techniques, we obtain a reduced system of differential equations

Concentric Plithogenic Hypergraph based on Plithogenic Hypersoft sets – A Novel Outlook [PDF]
Neutrosophic Sets and Systems, 2020 Plithogenic Hypersoft sets (PHS) introduced by Smarandache are the extensions of soft sets and hypersoft sets and it was further protracted to plithogenic fuzzy whole Hypersoft set to make it more applicable to multi attribute decision making ...

Multistability, intermittency, and hybrid transitions in social contagion models on hypergraphs [PDF]
Nature Communications, 2021 Social interactions often occur in groups of individuals, which can be mathematically represented as hypergraphs. In this study, the authors analyze the appearance of multistability, intermittency, and hybrid phase transitions in social contagion models ...

Hypergraph Convolutional Networks via Equivalency between Hypergraphs and Undirected Graphs [PDF]
arXiv.org, 2022 As a powerful tool for modeling complex relationships, hypergraphs are gaining popularity from the graph learning community. However, commonly used frameworks in deep hypergraph learning focus on hypergraphs with edge-independent vertex weights (EIVWs ...
