Mean-field optimal control with stochastic leaders
Sebastian Zimper, Ana Djurdjevac, Carsten Hartmann +2
The paper analyzes large stochastic agent systems steered by a few stochastic leaders, derives a partial mean‑field limit described by a coupled McKean‑Vlasov and controlled Itô SD…

Collective variables for homophily-driven network rewiring dynamics
Sören Nagel, Stefanie Winkelmann, Péter Koltai +2
Stochastic network rewiring processes, in which edges dynamically rewire based on fixed node attributes, are widely used in applications ranging from social dynamics to neuroscienc…

Clustering in co-evolving opinion dynamics: reduced SPDE models
Sebastian Zimper, Nataša Djurdjevac Conrad, Federico Cornalba +1
Clustering is a fundamental collective phenomenon in agent-based models (ABMs) of opinion dynamics. To study clustering in systems with co-evolving social and opinion variables, we…
