Optimal strategies for controlled growth in metastable Kawasaki dynamics
Simone Baldassarri, Maike C. de Jongh
In this paper, we develop a Markov decision process (MDP) formulation for the low--temperature metastable Ising model evolving according to Kawasaki dynamics in a finite box of the…
Infection models on dense dynamic random graphs
Simone Baldassarri, Peter Braunsteins, Frank den Hollander +1
We consider Susceptible-Infected-Recovered (SIR) models on dense dynamic random graphs, in which the joint dynamics of vertices and edges are co-evolutionary, i.e., they influence…
Metastable opinion dynamics with hidden preferences: an Ising model with neutral agents
Simone Baldassarri, Vanessa Jacquier, Alessandro Zocca
We introduce a new Ising-type framework for opinion dynamics that explicitly separates private preferences from publicly expressed binary opinions and naturally incorporates neutra…
Parameter estimation in interacting particle systems on dynamic random networks
Simone Baldassarri, Jiesen Wang
In this paper we consider a class of interacting particle systems on dynamic random networks, in which the joint dynamics of vertices and edges acts as one-way feedback, i.e., edge…
Functional central limit theorem for the subgraph count of the voter model on dynamic random graphs
Simone Baldassarri, Nikolai Kriukov
In this paper we consider two-opinion voter models on dynamic random graphs, in which the joint dynamics of opinions and graphs acts as one-way feedback, i.e., edges appear and dis…
Opinion dynamics on dense dynamic random graphs
Simone Baldassarri, Peter Braunsteins, Frank den Hollander +1
We consider two-opinion voter models on dense dynamic random graphs. Our goal is to understand and describe the occurrence of consensus versus polarisation over long periods of tim…
