The complexity of many biological, social and technological systems stems from the richness of the interactions among their units. Over the past two decades, a great variety of complex systems has been successfully described as networks whose interacting pairs of nodes are connected by links. Yet, from face-to-face human communications to chemical and biological reactions, many interactions in networked systems cannot be described by simple dyads, as they can occur in groups composed by any number of units. Until recently, little attention has been devoted to such high-order architecture of real complex systems. However, a mounting body of evidence is showing that taking the high-order structure of these systems into account can greatly enhance our modelling capacities and help us to understand and predict their emerging dynamical behaviours.
The aim of this satellite is to provide a coherent window on the emerging subfield of networks beyond pairwise interactions. In particular, we will discuss how to represent higher-order interacting systems, and how to unify the diverse frameworks most commonly used to describe higher-order interactions, highlighting the numerous links between the existing concepts and representations. We also focus on recent advancements on the structural measures developed to characterize the structure of these systems, on the related generative models, and on novel emergent phenomena characterizing landmark dynamical processes when extended beyond pairwise interactions.

The satellite will have space for contributed talks in the form of 10/15-minute presentations. Participants are invited to submit an abstract in PDF format using the EasyChair website (button below).
Topics of interest relate to higher-order structures (HOrSs) and network topology, and include
Higher-order representations of interacting systems
Structural measures for HOrS
Generative models for HOrS (growing simplicial complexes, bipartite graphs, hypergraphs etc.)
Dynamical processes on HOrS (diffusion, spreading, synchronization, games etc.)
Applications to real-world systems (TDA)
Stochastic topology
Topological properties of network embedding into metric or pseudo-metric spaces
Topological properties of geometric representations of networks
Submissions should be at most 2 pages long (figure included) and should include: title, author(s), affiliation(s), and e-mail address(es).
Submissions will be evaluated and selected by the Program Committee members, based on the adherence with the theme of the satellite, originality and scientific soundness.
Deadline for submissions: April 23.
Acceptance notifications: Early May.
Authors not already registered on EasyChair should sign up for an account (please note: make sure to use the same email address as the one used for the conference registration).
