Non-Abelian Topological Approach to Non-Locality of a Hypergraph State

open access: yesEntropy, 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.

Multi-grained hypergraph interest modeling for conversational recommendation

open access: yesAI Open, 2023
Conversational recommender system (CRS) interacts with users through multi-turn dialogues in natural language, which aims to provide high-quality recommendations for user’s instant information need.

AHD-SLE: Anomalous Hyperedge Detection on Hypergraph Symmetric Line Expansion

open access: yesAxioms
Graph 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.

Hypergraph Computation

open access: yesEngineering
Practical real-world scenarios such as the Internet, social networks, and biological networks present the challenges of data scarcity and complex correlations, which limit the applications of artificial intelligence. The graph structure is a typical tool

The Existence of Quasi Regular and Bi-Regular Self-Complementary 3-Uniform Hypergraphs

open access: yesDiscussiones 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(

Constructible hypergraphs

open access: yesDiscrete Mathematics, 1991
AbstractThe class M of finite manuals (i.e. hypergraphs formed by the cliques of finite graphs) is closed under the formation of sums and products. We define the class of constructible hypergraphs to be the smallest subclass of M which contains all finite classical manuals (i.e.

Partitive hypergraphs

open access: yesDiscrete Mathematics, 1981
AbstractWe define a new class of hypergraphs (partitive hypergraphs) which generalizes both, the set of all externally related subsets of a graph and the set of all committees of an hypergraph.We give a characterization of the partitive hypergraphs and moreover of those which are associated with hypergraphs or graphs.

Discrepancy of Sums of two Arithmetic Progressions

open access: yes, 2007
Estimating the discrepancy of the hypergraph of all arithmetic progressions in the set $[N]=\{1,2,\hdots,N\}$ was one of the famous open problems in combinatorial discrepancy theory for a long time.

Hypergraph animals

open access: yesPhysical Review E
Here 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 ...
