Analyzing Dynamic Hypergraphs with Parallel Aggregated Ordered Hypergraph Visualization

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2021
Parallel Aggregated Ordered Hypergraph(PAOH) is a novel technique to visualize dynamic hypergraphs. Hypergraphs are a generalization of graphs where edges can connect several vertices.

A Note on Packing of Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We say that two n-vertex hypergraphs H1 and H2 pack if they can be found as edge-disjoint subhypergraphs of the complete hypergraph Kn. Whilst the problem of packing of graphs (i.e., 2-uniform hypergraphs) has been studied extensively since seventies ...

Independence densities of hypergraphs [PDF]

open access: yes, 2013
We consider the number of independent sets in hypergraphs, which allows us to define the independence density of countable hypergraphs. Hypergraph independence densities include a broad family of densities over graphs and relational structures, such as ...

Hypergraph Partitioning [PDF]

open access: yes, 2011
Hypergraphs are generalization of graphs where each edge (hyperedge) can connect more than two vertices. In simple terms, the hypergraph partitioning problem can be defined as the task of dividing the vertices of hypergraph into two or more roughly equal sized parts such that a cost function on the hyperedges connecting vertices in different parts is ...

Granulation of Hypernetwork Models under the q-Rung Picture Fuzzy Environment

open access: yesMathematics, 2019
In this paper, we define q-rung picture fuzzy hypergraphs and illustrate the formation of granular structures using q-rung picture fuzzy hypergraphs and level hypergraphs.

Hypergraph coverings and Ramanujan Hypergraphs

open access: yes, 2023
In this paper we investigate Ramanujan hypergraphs by using hypergraph coverings. We first show that the spectrum of a $k$-fold covering $\bar{H}$ of a connected hypergraph $H$ contains the spectrum of $H$, and that it is the union of the spectrum of $H$ and the spectrum of an incidence-signed hypergraph with $H$ as underlying hypergraph if $k=2 ...

Complex Neutrosophic Hypergraphs: New Social Network Models

open access: yesAlgorithms, 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 ...

Annotated hypergraphs: models and applications

open access: yesApplied Network Science, 2020
Hypergraphs offer a natural modeling language for studying polyadic interactions between sets of entities. Many polyadic interactions are asymmetric, with nodes playing distinctive roles.

Toric algebra of hypergraphs [PDF]

open access: yes, 2013
The edges of any hypergraph parametrize a monomial algebra called the edge subring of the hypergraph. We study presentation ideals of these edge subrings, and describe their generators in terms of balanced walks on hypergraphs.
