Learning effective models from network dynamics data with multiple initial conditions using weak form SINDy
Moyi Tian, Daniel A. Messenger, Vanja Dukic +2
Social systems consist of networks of individuals who influence one another through social interactions. Studying how processes evolve on these networks can help us better understa…
Learning dynamics from online-offline systems of LLM agents
Moyi Tian, George Mohler, P. Jeffrey Brantingham +1
Online information is increasingly linked to real-world instability, especially as automated accounts and LLM-based agents help spread and amplify news. In this work, we study how…
Modelling the spillover from online engagement to offline protest: stochastic dynamics and mean-field approximations on networks
Moyi Tian, P. Jeffrey Brantingham, Nancy Rodríguez
Social media is transforming various aspects of offline life, from everyday decisions such as dining choices to the progression of conflicts. In this study, we propose a coupled mo…
The effect of protest management strategies on protesting activity and social tension: a mathematical perspective
Wuyan Wang, Timothy Wessler, Nancy Rodríguez +1
Protest activity, a constitutionally protected right in the United States under the First Amendment, serves as a key tool for individuals with limited individual influence to unite…
A dynamical system model of gentrification: Exploring a simple rent control strategy
Jonathan D. Shaw, Juan G. Restrepo, Nancy Rodríguez
Motivated by the need to understand the factors driving gentrification, we introduce and analyze two simple dynamical systems that model the interplay between three potential drive…
