AHD-SLE: Anomalous Hyperedge Detection on Hypergraph Symmetric Line Expansion
AxiomsGraph anomaly detection aims to identify unusual patterns or structures in graph-structured data. Most existing research focuses on anomalous nodes in ordinary graphs with pairwise relationships.

The Existence of Quasi Regular and Bi-Regular Self-Complementary 3-Uniform Hypergraphs
Discussiones Mathematicae Graph Theory, 2016 A k-uniform hypergraph H = (V ;E) is called self-complementary if there is a permutation σ : V → V , called a complementing permutation, such that for every k-subset e of V , e ∈ E if and only if σ(e) ∉ E. In other words, H is isomorphic with H′ = (V ; V(

Non-Abelian Topological Approach to Non-Locality of a Hypergraph State
Entropy, 2015 We present a theoretical study of new families of stochastic complex information modules encoded in the hypergraph states which are defined by the fractional entropic descriptor.

Discrete Mathematics, 1978 AbstractUn hypergraphe arboré est l'hypergraphe d'une familie de sous-arbres d'un arbre. Un hypergraphe est arboré si, et seulement si, il a la propriété de Helly et sa représentation triangulée; cette derniére propriété est ensuite remplacée par une condition sur les cycles de l'hypergraphe.

Physical Review EHere we introduce simple structures for the analysis of complex hypergraphs, hypergraph animals. These structures are designed to describe the local node neighbourhoods of nodes in hypergraphs. We establish their relationships to lattice animals and network motifs, and we develop their combinatorial properties for sparse and uncorrelated hypergraphs ...

Community detection in hypergraphs via mutual information maximization
Scientific ReportsThe hypergraph community detection problem seeks to identify groups of related vertices in hypergraph data. We propose an information-theoretic hypergraph community detection algorithm which compresses the observed data in terms of community labels and ...
