Signal propagation in complex networks drives epidemics, is responsible for information
going viral, promotes trust and facilitates moral behavior in social groups, enables the …

Network-based modeling of complex systems and data using the language of graphs has
become an essential topic across a range of different disciplines. Arguably, this graph-based …

Summary CompleX Group Interactions (XGI) is a library for analyzing higher-order networks.
Such networks are used to model interactions of arbitrary size between entities in a complex …

Individuals who interact with each other in social networks often exchange ideas and
influence each other's opinions. A popular approach to study the spread of opinions on …

How can minorities of individuals overturn social conventions? The theory of critical mass
states that when a committed minority reaches a critical size, a cascade of behavioural …

Agent-based models of opinion dynamics allow one to examine the spread of opinions
between entities and to study phenomena such as consensus, polarization, and …

Dynamical systems on hypergraphs can display a rich set of behaviors not observable for
systems with pairwise interactions. Given a distributed dynamical system with a putative …

We study the effect of group interactions on the emergence of consensus in a spin system.
Agents with discrete opinions {0, 1} form groups. They can change their opinion based on …

Every day, people inform themselves and create their opinions on social networks. Although
these platforms have promoted the access and dissemination of information, they may …

The higher-order interactions in complex systems are gaining attention. Extending the
classic bounded confidence model where an agent's opinion update is the average opinion …
