Parameter inference for partially observed branching processes
Simone Baldassarri, Michel Mandjes, Jiesen Wang
In this paper, we study an age-dependent branching process. In the simplest setting, the population is divided into two age groups, namely juveniles and adults. Our objective is to…
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…
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…
Homogeneous nucleation for two-dimensional Kawasaki dynamics
Simone Baldassarri, Alexandre Gaudillière, Frank den Hollander +3
This is the third in a series of three papers in which we study a lattice gas subject to Kawasaki dynamics at inverse temperature in a large finite box $Î_β\subset \mathbb…
