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 ...

Threshold hypergraphs

open access: yesDiscrete Mathematics, 1985
Threshold graphs were introduced by \textit{V. Chvátal} and \textit{P. L. Hammer} [Ann. Discrete Math. 1, 145-162 (1977; Zbl 0384.90091)]. They gave three equivalent characterizations of these graphs. These characterizations were generalized for hypergraphs by \textit{M. Ch. Golumbic} [Combinatorics, Keszthely 1976, Colloq. Math.

Finding the K shortest hyperpaths using reoptimization [PDF]

open access: yes
The shortest hyperpath problem is an extension of the classical shortest path problem and has applications in many different areas. Recently, algorithms for finding the K shortest hyperpaths in a directed hypergraph have been developed by Andersen ...

The upper chromatic number of quasi-interval co-hypergraphs

open access: yesLe Matematiche, 1997
We investigate the structural and colouring properties of clique hyper-graphs of interval graphs called the quasi-interval hypergraphs. We find the conditions when they are interval hypergraphs. The upper chromatic number for the clique co-hypergraphs of

Analysis of hub parameters in fuzzy hypergraphs extending to intuitionistic fuzzy threshold hypergraphs: Applications in designing transport networks in amusement parks using hub hyperpaths [PDF]

open access: yesNotes on IFS
A hypergraph is a generalization of a graph where an edge can connect any number of vertices. In this paper, many different aspects of fuzzy hypergraphs and their applications are examined.

Connectivity in Hypergraphs

open access: yes, 2018
In this paper we consider two natural notions of connectivity for hypergraphs: weak and strong. We prove that the strong vertex connectivity of a connected hypergraph is bounded by its weak edge connectivity, thereby extending a theorem of Whitney from ...

Influence Maximization in Hypergraphs [PDF]

open access: yes, 2022
Influence maximization in complex networks, i.e., maximizing the size of influenced nodes via selecting K seed nodes for a given spreading process, has attracted great attention in recent years. However, the influence maximization problem in hypergraphs,

Census and Analysis of Higher-Order Interactions in Real-World Hypergraphs

open access: yesBig Data Mining and Analytics
Complex systems can be more accurately described by higher-order interactions among multiple units. Hypergraphs excel at depicting these interactions, surpassing the binary limitations of traditional graphs.

The subdivision of hypergraphs

open access: yes, 2023
Hypergraphs, as a generalization of simplicial complexes, have long been a subject of interest in their geometric interpretation. The subdivision of simplicial complexes can, to some extent, provide insights into the geometry of simplicial complexes.
