A risk assessment framework for interacting tipping elements Open
Tipping elements, such as the Greenland Ice Sheet, the Atlantic meridional ocean circulation (AMOC) or the Amazon rainforest, interact with one another and with other non-linear systems such as the El-Nino Southern Oscillation (ENSO). In d…
The impact of mobility costs on cooperation and welfare in spatial social dilemmas Open
From over-exploitation of resources to urban pollution, sustaining well-being requires solving social dilemmas of cooperation. Often such dilemmas are studied assuming that individuals occupy fixed positions in a network or lattice. In spa…

When individuals interact in a social network their opinions can change, at times quite significantly, as a result of social influence. \n \nIn elections, for example, while they might initially support one candidate, what their friends sa…
Enabling imitation-based cooperation in dynamic social networks Open
The emergence of cooperation among self-interested agents has been a key concern of the multi-agent systems community for decades. With the increased importance of network-mediated interaction, researchers have shifted the attention to the…

Predicting Voting Outcomes in the Presence of Communities, Echo Chambers and Multiple Parties Open
A recently proposed graph-theoretic metric, the influence gap, has shown to be a reliable predictor of the effect of social influence in two-party elections, albeit only tested on regular and scale-free graphs. Here, we investigate whether…
