Group dynamics shape contagion onsets and multistable active phases under collective reinforcement
Santiago Lamata-Otín, Federico Malizia, Leah A. Keating +4
Group-based reinforcement can induce discontinuous transitions from inactive to active phases in higher-order contagion models. However, these results are typically obtained on sta…
Loops, not groups: Long cycles are responsible for discontinuous phase transitions in higher-order network contagions
Leah A. Keating, Laurent Hébert-Dufresne
We study a self-consistent approach to introduce higher-order effects in a branching process model of complex contagion on clustered networks. Branching processes operate over an i…
An Approximate-Master-Equation Formulation of the Watts Threshold Model on Hypergraphs
Leah A. Keating, Kwang-Il Goh, Mason A. Porter
In traditional models of behavioral and opinion dynamics on networks, researchers suppose that interactions occur between pairs of individuals. However, in reality, social interact…
Effectiveness of Contact Tracing on Networks with Cliques
Abbas K. Rizi, Leah A. Keating, James P. Gleeson +2
Contact tracing, the practice of isolating individuals who have been in contact with infected individuals, is an effective and practical way of containing disease spread. Here, we…
A generating-function approach to modelling complex contagion on clustered networks with multi-type branching processes
Leah A. Keating, James P. Gleeson, David J. P. O'Sullivan
Understanding cascading processes on complex network topologies is paramount for modelling how diseases, information, fake news and other media spread. In this paper, we extend the…
A multi-type branching process method for modelling complex contagion on clustered networks
Leah A. Keating, James P. Gleeson, David J. P. O'Sullivan
Complex contagion adoption dynamics are characterised by a node being more likely to adopt after multiple network neighbours have adopted. We show how to construct multi-type branc…
