Special Issue Information
Dear Colleagues,
In the last few decades, network science has emerged as a breakthrough field in order to study and investigate complex systems.
A graph (or network) is the archetype of (organized) complexity, where a set of nodes are connected to each other by mutual correlations (edges). Such topological and semantic data structures have been widely used to model telecommunication and computer networks, biological networks and social networks, just to name a few.
However, an intrinsic drawback when dealing with graphs is that they only account for pairwise relationships between nodes; indeed, by definition, an edge can only connect two nodes. This somehow limits the modelling power offered by graphs, yielding an incomplete description of the system under investigation.
Hypergraphs overcome these limitations by allowing hyperedges to connect simultaneously more than two nodes. The greater modelling capabilities of multi-way relationships have been demonstrated in fields such as biology (e.g., protein-protein interaction networks) and social networks (e.g., collaboration networks). Yet the power of hypergraphs is not limited to a mere representation of the data. Hypergraphs and simplicial complexes also play a key role in the emergent field of topological data analysis, whose aim is to analyze a set of data (or point clouds) using techniques derived from topology and mathematics. In fact, rather than analyzing the data itself (which can be difficult due to noise, high-dimensionality, and so on), one can build a filtered set of simplicial complexes and study their properties.
This Special Issue aims to collect high-quality research papers within the research field of hypergraphs, embracing applications, theoretical conceptualizations and computational aspects. Papers bridging the gap between hypergraphs and machine learning are particularly of interest. Position and survey papers are also welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
