This paper deals with three generalizations of threshold graphs to hypergraphs proposed by M. Ch. Golumbic. Answering a question of M. Ch. Golumbic we show that these three definitions are not equivalent.

Connected components in networks with higher-order interactions
We address the problem of defining connected components in hypergraphs, which are models for systems with higher-order interactions. For graphs with dyadic interactions, connected components are defined in terms of paths connecting nodes along the graph.

Matchings in balanced hypergraphs
The present work deals with the matching and vertex cover problem in balanced hypergraphs. This class of hypergraphs is, according to the definition by Berge in the 70s, one possible generalization of bipartite graphs.

Homomorphisms of quantum hypergraphs
We introduce quantum homomorphisms between quantum hypergraphs through the existence of perfect strategies for quantum non-local games, canonically associated with the quantum hypergraphs.

Colourings of hypergraphs [PDF]
In Chapter 2, we describe some generalized chromatic numbers of graphs. In Chapter 3, we describe how these may be regarded as chromatic numbers of associated hypergraphs.

Random recursive hypergraphs grow by adding, at each step, a vertex and an edge formed by joining the new vertex to a randomly chosen existing edge. The model is parameter-free, and several characteristics of emerging hypergraphs admit neat expressions ...

Abstract We showthat for every integer $k\geqslant 3$ the set of Turán densities of $k$-uniform hypergraphs has an accumulation point in $[0,1)$. In particular, $1/2$ is an accumulation point for the set of Turán densities of $3$-uniform hypergraphs.

Infinite hypergraphs I. Basic properties
Basic properties of the category of infinite directed hyperedge-labelled hypergraphs are studied. An algebraic structure is given which enables us to describe such hypergraphs by means of infinite expressions. It is then shown that two expressions define

Entropy-based models to randomise real-world hypergraphs
Network theory has often disregarded many-body relationships, solely focusing on pairwise interactions: neglecting them, however, can lead to misleading representations of complex systems.

Extending Graph-Based LP Techniques for Enhanced Insights Into Complex Hypergraph Networks
Many real-world problems can be modelled in the form of complex networks. Social networks such as research collaboration networks and facebook, biological neural networks such as human brains, biomedical networks such as drug-target interactions and ...
